This is something you can look up in your text but here they are.

Boyle's law==The volume of a gas at constant temperature is inversely proportional to the pressure.
Charles' law==The volume of a gas at constant pressure is directly proportional to the temperature.
Check it out in your text to make sure I have it correct.

I'm in 5th grade they don't let us take home the books - If in Charles's law when temperature of a gas increases if you keep pressure constant then what happens?

Thanks for letting me know your grade. That helps. In my first response, I wrote that Charles' law states volume and pressure are directly proportional. Directly means that when one goes up the other one goes up. When one goes down, the other goes down. Therefore, if T increases, volume increases. If T decreases, volume decreases. One thing to remember is that decreasing T from say 200 C to 100 C will NOT decrease volume by 2 BECAUSE the T must be measured in Kelvin, not Celsius. We can convert 200 C to 273 + 200 = 473 Kelvin and 100 C to 273 + 100 = 373 Kelvin. So decreasing T from 200 C to 100 C will decrease the volume from whatever it was to that number times (373/473). I hope this helps.

Boyle's Law and Charles's Law are two fundamental gas laws that relate the pressure, volume, and temperature of a gas.

Boyle's Law states that at a constant temperature, the pressure and volume of a gas are inversely proportional to each other. This means that as the volume of a gas decreases, its pressure will increase, and vice versa, as long as the temperature remains constant.

Charles's Law, on the other hand, states that at a constant pressure, the volume and temperature of a gas are directly proportional to each other. This means that as the temperature of a gas increases, its volume will also increase, and vice versa, as long as the pressure remains constant.

Both laws can be summarized with the following equations:

Boyle's Law: P₁V₁ = P₂V₂
where P₁ and V₁ are the initial pressure and volume, and P₂ and V₂ are the final pressure and volume.

Charles's Law: V₁/T₁ = V₂/T₂
where V₁ and T₁ are the initial volume and temperature, and V₂ and T₂ are the final volume and temperature.

To understand and apply Boyle's Law and Charles's Law, you will need to know the initial and final values of pressure, volume, and temperature of a gas, while keeping one of the variables constant. By rearranging the equations, you can solve for the unknown variables.

It is important to note that Boyle's Law and Charles's Law assume ideal gas behavior and require the gas to be held at a constant amount (moles) and not undergo a phase change.
