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.
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.

Calorimetry is the science of measuring heat changes in a chemical or physical process. It involves using a calorimeter to measure the heat released or absorbed during a reaction to determine the energy change. This information is crucial for understanding the thermodynamic properties of substances and reactions.
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.
It depends. There are two types of chemical reaction int his sense. Exothermic reactions release energy and endothermic reactions absorb it.
The enthalpy of reaction measures the amount of heat absorbed or released during a chemical reaction at constant pressure. It indicates whether a reaction is exothermic (heat is released) or endothermic (heat is absorbed).
Chemical reactions usually involve change of heat due to energy absorbed or evolved during reaction.
when a chemical change occurs, chemical bonds are broken up
Heat
The bomb calorimetry equation used to calculate the heat released or absorbed during a chemical reaction is Q mcT, where Q is the heat energy, m is the mass of the substance, c is the specific heat capacity, and T is the change in temperature.
Heat
One can determine the change in enthalpy (H) for a chemical reaction by measuring the heat released or absorbed during the reaction using a calorimeter. The difference in heat between the products and reactants gives the enthalpy change.
The energy will of course also be absorbed by the object. For example, when an object is in sunlight and absorbs part of the light, its temperature will increase.
