Which gas is the most compressible?
Which gas is the most compressible? helium Is a gas compressible? If we put pressure on a solid or a liquid, there is essentially no change in volume. The kinetic-molecular theory explains why gases are more compressible than either liquids or solids. Gases are compressible because most of the volume of a gas is composed […]
How many sides are there to a compression refrigeration cycle?
How many sides are there to a compression refrigeration cycle? The Vapor Compression Refrigeration Cycle involves four components: compressor, condenser, expansion valve/throttle valve and evaporator. It is a compression process, whose aim is to raise the refrigerant pressure, as it flows from an evaporator. Can you recharge your home AC yourself? While it is possible […]

What is the boiling pressure of water?
What is the boiling pressure of water? 100 °C What temperature does water boil at PSI? When you cook in a regular pot at atmospheric pressure (14.7 pounds per square inch [psi]), water boils at 100°C (212°F). Inside a pressure cooker, the pressure can increase by an additional 15 psi, to almost 30 psi. At that […]

What is meant by the change of state?
What is meant by the change of state? Changes of state are physical changes in matter. They are reversible changes that do not involve changes in matter’s chemical makeup or chemical properties. Common changes of state include melting, freezing, sublimation, deposition, condensation, and vaporization. Can the change of state be reversed? State changes are reversible […]
