What is average kinetic energy?

Two gas cylinders are identical. One contains the monatomic gas argon (Ar), and the other contains an equal mass of the monatomic gas krypton (Kr). The pressures in the cylinders are the same, but the temperatures are different. Determine the ratio of...

a. What is the average kinetic energy of a nitrogen molecule at STP? b. What is the total translational kinetic energy of 5.00 mol of N2 molecules at 50°C? If you can just explain how to do it I can calculate the answer. Im just confused cus I know...

A. The kinetic energy of gas molecules is inversely proportional to the Kelvin temperature of the gas. B. The kinetic energy of gas molecules is directly proportional to the Kelvin temperature of the gas. C. The kinetic energy of gas molecules is unaffected...

Consider the changes of state for a simple water molecule that goes from a solid to a liquid to a gas from the perspective of its average kinetic energy. What statement is true? 1. As the ice melts and becomes a gas, the kinetic energy decreases. 2....

A toy car has a kinetic energy of 12 J. What is its kinetic energy after a frictional force of 0.5 N has acted on it for 7 m? J

The 4.00 kg cannon ball is again taken to the top of the other building and held 40.0 m above the ground. This time it is tossed downward with a speed of 8.00 m/s. Using energy conservation and assuming negligible air resistance, calculate its a) kinetic...
