Find the temperature of the air contained inside of a balloon full of 2 moles of helium, in which its particles move at a mean velocity of 480m/s. What is the internal energy of the gas?
We want to measure the temperature of 3.4 moles of gas that we know have an internal energy of 50000J. Do we need to use a thermometer? Or can we predict its temperature just by looking at the data we have?
I would like to make a gas double in volume while keeping a constant pressure. How much do I need to raise the temperature? What if I wanted to double the volume while keeping a constant temperature?
An adiabatic transformation produces 48300J of work. The transformation starts at a temperature of 300K and a pressure of 1.3Pa. After it ends, the volume of the gas has doubled. Find the initial volume, the final pressure and the final temperature.
