How ESB stands to gain from EU energy market?

Does melting lose or gain thermal energy?

• Does: -Melting gain or lose thermal energy? -Freezing gain or lose thermal energy? -Vaporization gain or lose thermal energy? -Condensation gain or lose thermal energy? -Sublimation gain or lose thermal energy?

• Answer:

  if you talk about water, H2O: water gains thermal energy when it goes from a cold state to a warmer state i.e. ice to liquid water, liquid to vapor, vapor to steam. and vice versa the object exerting the heat on the H2O molecules loses thermal energy for example if you hold an ice cube in your hand your hand gets colder and the ice melts thats because your hand is passing thermal energy to the ice so the hand loses thermal energy and the ice gains thermal so for the above: Melting is a gain freezing is a loss vaporizing is a gain condensing is a loss Sublimation is a gain
