Questions and Answers

Define surface tension and give units.

Surface tension is the force acting in the surface of a liquid. It is measured in N/m.

What is the effect of temperature on the speeds and kinetic energy of gas molecules?

As temperature increases, the speeds and kinetic energy of gas molecules also increase.

State Avogadro’s law.

Avogadro’s law states that equal volumes of gases at the same temperature and pressure contain equal numbers of molecules.

What is an Ideal gas?

An ideal gas is a hypothetical gas whose molecules occupy negligible space and have no interactions, following the ideal gas law PV = nRT. Signup and view all the answers
