# Boyles Law and Charles Law Gizmo: An Engaging Simulation for Science and Math Learning

## Boyles Law And Charles Law Gizmo Answer Key Zip

Have you ever wondered how gas behaves under different conditions of pressure and temperature? If so, you might be interested in learning about two important gas laws: Boyles law and Charles law. These laws describe how the volume of a gas changes when its pressure or temperature changes. In this article, you will learn what these laws are, how to use a gizmo to explore them, and how to answer some questions based on them. You will also see some examples of how these laws are applied in real life.

## What is Boyles law?

Boyles law is a gas law that states that the pressure and volume of a gas are inversely proportional, as long as the temperature and amount of gas are constant. This means that when the pressure increases, the volume decreases, and vice versa. The formula for Boyles law is:

P1V1 = P2V2

where P1 and V1 are the initial pressure and volume of the gas, and P2 and V2 are the final pressure and volume of the gas.

For example, if you have a balloon filled with air at 1 atm (atmosphere) of pressure and 10 L (liters) of volume, and you squeeze it until its volume becomes 5 L, what will be its new pressure? Using Boyles law, you can calculate:

P1V1 = P2V2

(1 atm)(10 L) = P2(5 L)

P2 = (1 atm)(10 L) / (5 L)

P2 = 2 atm

The new pressure will be 2 atm.

## What is Charles law?

Charles law is another gas law that states that the volume and temperature of a gas are directly proportional, as long as the pressure and amount of gas are constant. This means that when the temperature increases, the volume increases, and vice versa. The formula for Charles law is:

V1/T1 = V2/T2

where V1 and T1 are the initial volume and temperature of the gas, and V2 and T2 are the final volume and temperature of the gas.

Note that the temperature must be measured in Kelvin (K), which is a unit of absolute temperature that starts from zero. To convert from Celsius (C) to Kelvin (K), you can use this formula:

K = C + 273.15

For example, if you have a balloon filled with air at 20 C (293.15 K) of temperature and 10 L of volume, and you heat it up until its temperature becomes 40 C (313.15 K), what will be its new volume? Using Charles law, you can calculate:

V1/T1 = V2/T2

(10 L)/(293.15 K) = V2(313.15 K)

V2= (10 L)(313.15 K) / (293.15 K)

V2= 10.68 L

The new volume will be 10.68 L.

## What are some applications of Boyles law and Charles law?

Boyles law and Charles law are not just theoretical concepts. They have many practical applications in science and engineering. Here are some examples of how these laws are used in real life.

### Boyles law applications

• Spray paint: As we saw earlier, spray paint works by using Boyles law. When the nozzle is pressed, the pressure of the gas inside the can decreases, and the volume increases. This pushes the paint out of the can with a high speed and force.

• Human breathing: Boyles law also explains how we breathe. When we inhale, our diaphragm contracts and our chest cavity expands. This lowers the pressure inside our lungs, and increases the volume. As a result, air flows into our lungs from the higher pressure outside. When we exhale, the opposite happens. Our diaphragm relaxes and our chest cavity shrinks. This raises the pressure inside our lungs, and decreases the volume. As a result, air flows out of our lungs to the lower pressure outside.

• Syringe: A syringe is a device that is used to inject or withdraw fluids from the body. It consists of a barrel, a plunger, and a needle. When the plunger is pulled back, the volume inside the barrel increases, and the pressure decreases. This creates a vacuum that sucks the fluid into the barrel through the needle. When the plunger is pushed forward, the volume inside the barrel decreases, and the pressure increases. This forces the fluid out of the barrel through the needle.

• Bicycle pump: A bicycle pump is a device that is used to inflate tires with air. It consists of a cylinder, a piston, a valve, and a hose. When the piston is pulled up, the volume inside the cylinder increases, and the pressure decreases. This allows air to enter the cylinder through the valve from the outside. When the piston is pushed down, the volume inside the cylinder decreases, and the pressure increases. This forces air out of the cylinder through the hose into the tire.

• Scuba diving: Scuba diving is an activity that involves diving underwater with a self-contained breathing apparatus. The apparatus consists of a tank that contains compressed air, a regulator that controls the flow of air, and a mouthpiece that delivers air to the diver. When a diver descends deeper into water, the pressure on their body increases due to water weight. This causes their lungs to compress and their volume to decrease. To compensate for this, they need to breathe air at a higher pressure from their tank. When a diver ascends back to surface, they need to exhale slowly and frequently to avoid lung damage due to rapid expansion.

### Charles law applications

the burner, its volume increases, and its density decreases. This makes it lighter than the cold air outside, and creates a buoyant force that lifts the balloon up. When air is cooled down by turning off the burner, its volume decreases, and its density increases. This makes it heavier than the warm air outside, and creates a downward force that brings the balloon down.

• Bursting of a deodorant bottle: As we saw earlier, a deodorant bottle works by using Boyles law. When the nozzle is pressed, the pressure of the gas inside the can decreases, and the volume increases. This pushes the paint out of the can with a high speed and force. However, if the deodorant bottle is exposed to high temperatures, such as sunlight or fire, Charles law comes into play. The temperature of the gas inside the can increases, and so does its volume. This creates a high pressure that can exceed the limit of the can's capacity. As a result, the can bursts and explodes.

• Bakery products: If you love bakery products like bread and cakes, you can thank Jacques Charles. Charles law application in real life can be seen in our kitchen too. When you bake bread or cake, you add yeast or baking powder to make them rise. These ingredients produce carbon dioxide gas when they react with water or heat. The gas bubbles expand inside the dough or batter as they are heated up in the oven. This increases their volume and makes them fluffy and soft.

• Turkey pop-up timer: A turkey pop-up timer is a device that helps you cook a turkey perfectly. It consists of a metal stem that is inserted into the thickest part of the turkey's breast, and a plastic indicator that pops up when the turkey is done. The metal stem contains a spring that is held in place by a drop of soft metal or wax. When the turkey reaches a certain temperature (usually 165 F), the metal or wax melts and releases the spring. This pushes the plastic indicator up and signals that the turkey is ready.

• Opening of a soda can: A soda can is another example of Charles law in action. A soda can contains carbonated water that has carbon dioxide gas dissolved under high pressure. When you open a soda can, you release some of the pressure inside. This lowers the temperature of the gas slightly, and causes some of it to escape as bubbles. This creates a hissing sound and a spray of liquid.

• Helium balloon on cold day: A helium balloon is a type of balloon that uses helium gas to float in air. Helium gas is lighter than air, and creates a buoyant force that lifts the balloon up. However, on a cold day, Charles law affects the helium balloon's behavior. The temperature of the helium gas inside the balloon decreases, and so does its volume. This reduces its buoyancy and makes it sink or shrink.
