Latent heat is released from a vapor when it condenses absorbed by a vapor when it condenses released from a liquid when it freezes absorbed by a liquid when it freezes released from a solid when it sublimes ( goes to vapor) absorbed by a solid when it sublimes

Latent heat is:

Explanation:

Matter needs to absorb or release heat in order to change from one state to another. This heat is known as latent heat because it is not used to raise the temperature (thus it is not recorded) but it is used for the state change.

When matter passes from a low energy state to a high energy state (solid ⇒ liquid ⇒ vapor) it absorbs heat, which results in higher kinetic energy of the molecules.

When matter passes from a high energy state to a low energy state (vapor ⇒ liquid ⇒ solid) it releases heat, and the molecules have less kinetic energy.

Therefore, latent heat is:

the potential energy of the reactants is 200j.

from the energy diagram, the energy of the product formed is 350j; this means that, this reaction is an endothermic reaction, because it absorbs energy from its environment.

a  solution  is always transparent, light passes through with no scattering from solute particles which are molecule in size. the  solution  is homogeneous and does not settle out. a colloid is intermediate between asolution  and a  suspension. while asuspension  will separate out a colloid will not.
