What is the relationship between average kinetic energy and the temperature of a gas ?

What is the relation between the average kinetic energy and pressure?

What is the relation between kinetic energy and temperature ?

Write the relationship between kinetic energy and linear momentum.

When a sample of an ideal gas is heated from 25^(@)C to 50^(@)C the average kinetic energy of the molecules increases. Which ratio gives the correct relationship between the average kinetic energies at the higher temperature to the lower temperature?
