GCSE Physics - Factors Affecting Gas Pressure #30

The video tutorial explains how gas particles create pressure by colliding with container walls. It discusses the factors affecting pressure, such as the number of collisions and the energy involved. The tutorial covers how temperature, concentration, and volume influence pressure, highlighting that increased temperature and concentration lead to higher pressure, while decreased volume also increases pressure. It also addresses the behavior of flexible containers, like balloons, where changes in temperature and concentration affect volume rather than pressure.

What happens to gas particles when they collide with the walls of a container?

• They merge with other particles.

• They rebound and change direction.

• They pass through the walls.

• They stop moving.

How does increasing the temperature of a gas affect its pressure?

• Pressure remains constant.

• Pressure increases as particles move faster and collide more forcefully.

• Pressure decreases as particles slow down.

• Pressure decreases as particles move further apart.

What is the effect of increasing the concentration of gas particles in a fixed volume?

• Pressure decreases as particles settle.

• Pressure remains unchanged.

• Pressure increases due to more collisions.

• Pressure decreases due to fewer collisions.

How does reducing the volume of a gas container affect the pressure?

• Pressure decreases as particles have more space.

• Pressure increases as particles collide more frequently.

• Pressure decreases as particles move slower.

• Pressure remains the same.

In a flexible container, what happens when the temperature of the gas increases?

• The container shrinks and pressure decreases.

• The container expands and pressure decreases.

• The container expands and pressure remains constant.

• The container remains the same size and pressure increases.
