Is latent heat only released and absorbed as radiation?

In summary, water can absorb kinetic energy from colliding air molecules to change its phase, and water transformed into ice can have its kinetic energy increased to balance out lost latent heat, resulting in a change back to water. However, it is important to stick to one scenario (either gaining or losing heat) as these questions are not directly related to the topic of water changing its phase due to colliding air molecules.

Can water simply absord the kinetic energy from colliding air molucules to change its phase?
And can water transformed into ice simply have the kinetic energy of its molecules increased to balance out the lost latent heat? Would not this again change ice into water?

Yes.

Pick a scenario and stick to it: the water is either losing heat or gaining heat (in net). Not both.

Also, these questions don't seem to be related to the title question, to which the answer is no.
 

Related to Is latent heat only released and absorbed as radiation?

1. What is latent heat?

Latent heat is the energy required to change the state of a substance without changing its temperature. This energy is either released or absorbed during a phase change, such as from solid to liquid or liquid to gas.

2. Is latent heat only released and absorbed as radiation?

No, latent heat can also be released and absorbed through conduction or convection. For example, when water evaporates, it absorbs latent heat from its surroundings through convection.

3. How is latent heat related to radiation?

Latent heat is not directly related to radiation. However, during a phase change, such as from liquid to gas, the energy required to overcome the intermolecular forces is often supplied through radiation.

4. Can latent heat be measured?

Yes, latent heat can be measured using various methods such as calorimetry or by measuring the change in temperature during a phase change. The amount of latent heat released or absorbed can also be calculated using the specific heat capacity and mass of the substance.

5. What are some real-life examples of latent heat?

Some common examples of latent heat include the melting of ice, evaporation of water, and condensation of water vapor. In these processes, energy is either absorbed or released, leading to changes in state without a change in temperature.
