Gas laws

What happens to the volume of a gas when the pressure decreases?

• The volume of the gas increases.

• The volume of the gas decreases.

• The volume of the gas remains the same.

• The volume of the gas becomes zero.

Define 'directly proportional relationship' in the context of gas laws.

• A relationship where one variable increases while the other decreases.

• A relationship where both variables remain constant.

• A directly proportional relationship means that as one variable increases, the other variable also increases.

• A relationship that only applies to solid materials.

What happens to the volume of a gas when the temperature increases?

• The volume of the gas increases.

• The volume of the gas decreases.

• The volume of the gas remains the same.

• The volume of the gas fluctuates randomly.

What is the relationship between volume and temperature?

• The volume of a gas is inversely proportional to its temperature when pressure is constant.

• The volume of a gas is directly proportional to its temperature when pressure is constant.

• The volume of a gas is independent of its temperature when pressure is constant.

• The volume of a gas is directly proportional to its pressure when temperature is constant.

What is the relationship between pressure and volume?

• Boyle's Law states that the pressure of a gas is inversely proportional to its volume when temperature is held constant.

• Pressure and volume are directly proportional to each other at constant temperature.

• Pressure is independent of volume in a closed system.

• Volume increases as pressure increases at constant temperature.

What is the effect of temperature on gas pressure?

• As temperature increases, the pressure of a gas increases if the volume is held constant.

• As temperature increases, the pressure of a gas decreases if the volume is held constant.

• Temperature has no effect on gas pressure regardless of volume.

• As temperature increases, the pressure of a gas remains constant regardless of volume.

What is the relationship between pressure and volume according to Boyle's Law?

• The relationship is a direct relationship; as pressure increases, volume increases.

• The relationship is an inverse relationship; as pressure increases, volume decreases.

• The relationship is a constant relationship; pressure and volume remain unchanged.

• The relationship is a proportional relationship; as pressure increases, volume increases at a constant rate.

Define 'inversely proportional relationship' in the context of gas laws.

• An inversely proportional relationship means that as one variable increases, the other variable decreases.

• An inversely proportional relationship means that both variables increase together.

• An inversely proportional relationship means that both variables decrease together.

• An inversely proportional relationship means that one variable remains constant while the other changes.

How does a gas behave under constant pressure when heated?

• It contracts and decreases in volume.

• It remains unchanged in volume.

• It expands and increases its volume.

• It turns into a liquid.

What happens to a balloon when it is taken to a higher altitude?

• The pressure increases, causing the volume of the balloon to decrease.

• The pressure decreases, causing the volume of the balloon to increase, which may lead to it popping.

• The temperature decreases, causing the balloon to deflate slowly.

• The balloon remains unchanged regardless of altitude.
