What does the specific heat of a reaction represent?
This is the quantity of energy needed to maintain all substances involved in a chemical reaction at the same temperature.
Energy is absorbed when a nucleus is split during a nuclear reaction?
No, energy is released rather than absorbed
What Stokes shift indicate?
When a crystal absorbs a photon, that energy becomes part of the crystal. When that same crystal releases a photon, that photon is taking energy away from the crystal. The Stokes Shift is a measure of the difference in wavelength (and thus energy) of photons absorbed by a crystal and then immediately re-emitted by that same crystal. The energy shift between the two photons is an indication of how much energy has been permanently absorbed by the crystal in the form of heat.
In an endothermic change is energy released?
No, energy is absorbed instead.
What is absorbed by an endothermic reaction?
energy
Name one quantity that must be know in order to determine the amount of heat associated with a body?
There are three: Energy absorbed by a body is directly proportional to the rise in temperature of a body Heat energy absorbed by a body is directly proportional to the mass of the body Heat energy absorbed by a body depends upon its nature and is commonly called specific heat capacity.

How is energy absorbed?
Energy is transfrerrd
What does the specific heat of a reaction represent?

Solar radiation that is not reflected by Earth's systems is absorbed This absorbed energy is then reradiates as what into space?
This absorbed energy is then re-radiated as heat
When water is vapourisied energy is absorbed or released?
absorbed
Can energy be absorbed when matter changes?
yes it can be absorbed
Does radiant energy produce heat energy when it strikes matter?
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.
Sun's energy is absorbed by what?
the suns energy is absorbed by the leaf to make food. this is called photosynthesis :)
What are three change of state in which energy is absorbed?
Energy is absorbed during melting, boiling and sublimation.
Where is most of the sun's energy absorbed in water?
Most of the sun's energy is absorbed near the surface.
