why internal energy of an ideal gas depends on temperature only??
satisfactory answer will be marked as brainliest answer
Answers
Answer:
Because the internal energy of a gas does not change when it is allowed to expand into a vaccum.In that sense, the internal energy is independent of pressure and volume, and therefore dependent only on temperature.
Explanation:
Answer:
Particles in an ideal gas are point masses. No size, no shape. The distances between particles are very large. Therefore no attraction or repulsion between particles. The only thing they can do is move about from one location to another. They collide with each other and change direction and velocity. But there is no change in energy because collisions are perfectly elastic. Therefore the only type of energy they have is kinetic energy. Temperature is a measure of the average kinetic energy of these particles. When temperature increases, the average kinetic energy increases (the particles move faster). When temperature decreases, they move slower.
