Module P7.4 Specific heat, latent heat and entropy
... reminds us that the heat ∆Q supplied to an object may enable it to do work ∆W as well as producing a temperature change associated with a change ∆U in its internal energy. The specific heat therefore depends on the way ∆Q is shared between ∆W and ∆U, i.e. it depends on the extent to which a sample i ...

The Second Law of Thermodynamics
... after every bounce, the ball does not rise quite as high as before. The reason is that the collision between the ball and the floor is inelastic, so that upon each impact some of the ball’s kinetic energy is dissipated among the molecules in the floor. After each bounce, the floor becomes a little bit ...
