Latent heat
when energy is absorbed it is called an endergonic reaction and when energy is released it is called an exergonic reaction
Molecular movement is directly related to temperature. As temperature increase, the additional energy is absorbed by the molecules. This energy is converted to motion energy and the molecules will move faster.
photosynthesise
a chemical change is taking place
The release of energy from food molecules in the absence of oxygen is called anaerobic respiration. When there is oxygen present it is called aerobic respiration.
Latent heat
To the extent to which the energy is absorbed, yes. Reflectivity and color determine how much energy is absorbed, but no matter can reflect 100% of the energy striking it. Some will be absorbed by the molecules.
Example for light energy is absorbed or released, Heat is released and absorbed, electrical energy absorbed or released...
Energy is absorbed because the iodine is going from a liquid to a gas. This means that the iodine molecules are moving faster so they had to have absorbed more energy to do this.
Photons absorbed by a solution "disappear" and the energy they brought with them is transferred into the solution. That energy appears in the "activity" of the atoms, molecules and/or ions in the solution. The kinetic energy of these particles will increase because of the added energy.
absorbed,released
the suns energy is absorbed by the leaf to make food. this is called photosynthesis :)
when energy is absorbed it is called an endergonic reaction and when energy is released it is called an exergonic reaction
When a substance is changing from liquid to gas, the energy, which is absorbed, causes the atoms (or molecules) to move at a higher rate of speed, so that they are not staying close together, like in the liquid state. So the absorbed energy increases the kinetic energy of the atoms (or molecules).
When water molecules melt, energy is absorbed. When water molecules evaporate, energy is also absorbed. When water molecules condense energy is released. When water molecules freeze energy is also released.
It is used for providing energy and necessary to stay alive
