Question 1.
What causes pressure in a gas?
Show hintHide hint
Think about particle motion and collisions.
Question 2.
How does temperature affect gas pressure?
Show hintHide hint
Consider heating a sealed container.
3Question 3.
What happens to the pressure in a gas when the volume decreases while keeping temperature constant?
- Pressure increases
- Pressure decreases
- Pressure remains constant
Show hintHide hint
Think about how gas particles are compressed.
4Question 4.
True or False: In a gas, particles have intermolecular forces.
- True
- False
Show hintHide hint
Consider the nature of gas particles.
Question 5.
A 2 L container holds a gas at a pressure of 1 atm. If the volume is halved while maintaining the same number of moles, what is the new pressure?
Show hintHide hint
Watch for how volume changes when solving.
Question 6.
Explain how increasing temperature in a fixed volume leads to increased pressure, using kinetic molecular theory.
Show hintHide hint
Connect to the behavior of fast-moving particles.
