Based on the text, which principle explains that increasing the speed of gas molecules hitting the walls of a container results in higher gas pressure?

Kinetic Theory of Gases

Which term describes the phenomenon where more gas molecules in a container lead to an increase in pressure?

When fluid splits into two streams upon entering the valve

What is the purpose of a process control valve?

To control the rate of fluid flow

How can a linear cylinder be used to produce rotary movement?

With appropriate mechanical linkages

According to Boyle's Law, what happens to the volume of an enclosed gas when the pressure increases?

The volume decreases

Which principle states that the volume of a gas is proportional to its absolute temperature if pressure is constant?

Charles's Law

What happens to the volume of a gas if its absolute temperature is increased at constant pressure, according to Charles's Law?

The volume increases

In a hydraulic system, what happens to the liquid as the temperature rises?
