The simulation encompasses several key principles:
- Boyle’s Law: The relationship between pressure and volume at constant temperature.
- Charles’s Law: The relationship between temperature and volume at constant pressure.
- Gay-Lussac’s Law: The relationship between pressure and temperature at constant volume.
- Combined Gas Law: The relationship involving pressure, volume, and temperature of a gas.
- Ideal Gas Law: The comprehensive equation PV = nRT, integrating all variables.

Common questions and solutions in the phet gas law simulation answer key
Below are some typical questions and how to approach their solutions, aligned with the answer key:
Question 1: How does increasing temperature affect the volume of a gas at constant pressure?
Answer: According to Charles’s Law, if pressure remains constant, increasing temperature will increase the volume proportionally. The simulation demonstrates this by heating the gas and observing the expansion.
Question 2: What happens to pressure when the volume is decreased at constant temperature?
Answer: Boyle’s Law states that pressure and volume are inversely related at constant temperature. Decreasing volume results in increased pressure, which can be verified by the simulation.
Question 3: How do you calculate the final pressure after changing temperature and volume?
Answer: Use the combined gas law:
\[ \frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2} \]
Solve for the unknown variable, substituting known values from the simulation.
