Front

In the process Y→Z, if Q is greater than zero, what can be said about W and ΔU?

Back

W=0 and ΔU>0

Front

Which of the following is NOT an assumption of the kinetic theory of gases?

Back

Gas molecules move with the same speed, known as the r.m.s. speed.

Front

Which statement does NOT represent the ideal gas law?

Back

Volume is directly proportional to pressure.

Front

What is the first law of thermodynamics?

Back

Energy cannot be created or destroyed, only transformed.

Front

Define an adiabatic process.

Back

A process in which no heat is exchanged with the surroundings.

Front

What is the significance of the absolute temperature scale?

Back

It starts at absolute zero, where molecular motion stops.

Front

What does the term 'enthalpy' refer to?

Back

The total heat content of a system, including internal energy and the product of pressure and volume.

Front

What is the relationship between pressure and volume in Boyle's Law?

Back

Pressure is inversely proportional to volume at constant temperature.
