Which of the following is NOT a valid explanation to describe the origin of pressure in a gas

Particles collide with each other

Particles collide with the walls of the container

Particles create a force at the wall

The force of the particles summed over an area is pressure

The pressure is a gas increases with increasing temperature. What would be the correct order of the explanation?

Higher temperatures have higher KE and thus higher speed

Faster molecules hit the walls harder

The collision frequency increases

The overall force of molecules increases

Thus pressure increases

In the equation P₁V₁ = P₂V₂ which of the following must be true for the gas.

Temperature is constant

Mass is constant

Temperature must be in Kelvin

Pressure must be in kilo Pascals

In the equation P₁/T₁ = P₂/T₂ which of the following must be true?

Mass of gas must be constant

Volume of gas must be constant

Temperature must be in Kelvin

Temperature must be constant

The More The Volume The Less The Temperature

The More The Temperature The Less The Pressure

The More The Volume The More The Pressure

The More The Pressure The Less The Volume

12.

What is constant in the Boyle's Law?

Temperature

Pressure

Volume

Length

Mass of gas

temperature, equally

mass, inversely

temperature, inversely

mass, equally

14.

Which best explains why increasing the pressure on a gas decreases the volume of the gas sample?

Increasing the pressure causes the gas particles to hit the container walls more often.

Increasing the pressure on a gas sample moves the gas particles closer together.

Increasing the pressure on a gas sample causes the kinetic energy to increase.
