Answer 1

Greater kinetic energy

Explanation :-

As we know that if a particle is in motion then it exhibits kinetic energy and its equation is given by 1/2mv² here we can see that the kinetic energy of a particle is directly proportional to v². Now if we increase the temperature of the system the particles gain energy and start moving faster due to which its kinetic energy increases. Therefore a particle in hot object has greater kinetic energy than the particle in colder object.

the potential energy is associated with intermolecular forces and is presumed to be zero in an ideal gas where the only molecular interactions are the perfectly elastic collisions between molecules. Therefore the internal energy of an ideal gas is entirely kinetic energy.

We generally assume that the gas is ideal if it's not provided in the question.
