How many moles of hydrogen are present?
What is the average translational kinetic energy of the hydrogen molecules?
What is the value of the product of pressure and volume at ?
Nuclear fusion reactions between hydrogen nuclei require the nuclei to approach each other at very great speeds. What temperature of a hydrogen plasma is needed to ensure that the hydrogen nuclei in the plasma have average kinetic energies of J?
How much mechanical energy is dissipated in the collision?
Assuming that the value of the molar heat capacity at constant volume for the bob plus the bullet is , calculate the temperature increase of the system due to the collision. Take the molecular mass of the system to be 220 g/mol.
