What does the variable 'V' represent in the Ideal Gas Law?

• Pressure of the gas

• Temperature of the gas

• Volume of the gas

• Amount of substance in moles

What is Charles's Law?

• Charles's Law states that the volume of a gas is directly proportional to its absolute temperature when the pressure and number of moles are held constant.

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

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

• Charles's Law states that the number of moles of a gas is directly proportional to its pressure when the volume is held constant.

What does the variable 'P' represent in the Ideal Gas Law?

• The volume of the gas

• The temperature of the gas

• The pressure of the gas

• The number of moles of the gas

What does the variable 'n' represent in the Ideal Gas Law?

What is the Combined Gas Law?

• It states that the volume of a gas is directly proportional to its temperature at constant pressure.

• It combines Boyle's Law and Charles's Law and relates pressure, volume, and temperature of a fixed amount of gas.

• It describes the relationship between the pressure and volume of a gas at constant temperature.

• It states that the pressure of a gas is inversely proportional to its volume at constant temperature.

What happens to the volume of a gas if the temperature increases while the pressure remains constant?

• The volume of the gas decreases.

• The volume of the gas remains the same.

• The volume of the gas increases.

• The volume of the gas fluctuates.

What happens to the pressure of a gas if the volume decreases while the temperature remains constant?

• The pressure of the gas decreases.

• The pressure of the gas remains constant.

• The pressure of the gas increases, according to Boyle's Law.

• The pressure of the gas fluctuates unpredictably.
