No. Rather released. As during the physical changes in the states of matter, there is breaking of bonds involved. Whenever bonds are broken, the atoms of that matter come closer and energy they give out is more as compared to energy taken while breaking bonds. Hence, Physical changes at the level of states of Matter are always Exothermic i.e. RELEASING HEAT.

Is melting of ice a physical process or a chemical process?
Physical. The chemical makeup of the water doesn't change, and no heat is absorbed or discharged (endo/exothermic).
What are energy changers?
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
What can be absorbed or released as the result if a chemical reaction?
Heat
If heat is produced by a chemical system?
An equal amount of heat will be absorbed by the surroundings.
If heat is released by chemical systems an equal amount of heat will be?
absorbed by the surroundings
Is light absorbed in physical change?
Heat absorption is a physical change. It can cause a change in state and/or a temperature increase, but the matter that is absorbing the heat does not change. It retains all of its physical and chemical properties that it had before absorbing the heat.

When light is absorbed what does it change to?
Heat
What can. Be absorbed or produced as the result of a chemical reaction?
heat, light
What can absorbed or produced as the result of a chemical reaction?
heat, light
Is heat a form of energy released during a chemical reaction?
Yes, heat is often released or absorbed during a chemical reaction. This is because chemical reactions involve the breaking and formation of chemical bonds, and the energy difference between these bonds is released or absorbed in the form of heat.
What are the signs that a chemical reactions had occurred?
Change in colour, energy(heat, light sound) is produced. or in the case of heat it can also be absorbed. a precipitate, or new product is formed such as gas.
Is water absorbed by a towel a physical or chemical change?
It is a physical change.
