What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
Will a chemical reaction that asborbs energy happen with out a source of energy?
No, a chemical reaction that absorbs energy is called an endothermic reaction. The transfer of heat from the surrounds into the substance. In reactions, energy is always CONVERTED, not created which means that nothing can be converted i.e. heat to chemical if there is no heat or initial energy.
What happens to energy during a change of state why is it a phisycal change?
During a change of state, such as melting or boiling, energy is either absorbed or released by a substance without changing its chemical composition. For example, when ice melts into water, it absorbs heat energy, while when water freezes, it releases heat energy. This process is considered a physical change because it affects the form of the substance but not its chemical identity; the molecules remain the same throughout the change.
What is a chemical reaction that absorbs heat energy and stores it the chemical bonds of the product?
An example of a chemical reaction that absorbs heat energy and stores it in the chemical bonds of the product is photosynthesis, where carbon dioxide and water react in the presence of sunlight to produce glucose and oxygen. The energy from sunlight is absorbed during the reaction and stored in the bonds of glucose.
How does an endothermic process differ from an exothermic process?
An endothermic phase change is when the substance absorbs energy from its surroundings (melting, vaporization).In an exothermic phase change the substance releases energy to its surroundings (freezing, condensation)..
The change in which ice absorbs energy and melts is a?
Endothermic reactions are those in which energy is absorbed during the reaction. Exothermic reactions are those in which heat is evolved during the reactions.When ice melts its absorbs energy in the form of heat so why it melts,
Is heat liberated or absorbed when a chemical change takes place?
It depends on the reaction. An exothermic reaction releases (liberates) energy and an endothermic reaction absorbs energy.
When a chemical reaction absorbs energy in the form of heat is called a?
Endothermic reactions.
A chemical reaction that absorbs energy in the form of heat is called?
Endothermic reaction
What is the best term to describe a chemical reaction that absorbs heat energy?
An endothermic reaction.
What is the relationship between the heat of reaction and a chemical reaction?
The heat of reaction is the amount of heat energy released or absorbed during a chemical reaction. It is a measure of the reaction's energy change. The relationship between the heat of reaction and a chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat). This information helps us understand the energy changes that occur during the reaction.
Is butter melting in a pan a physical change that absorbs energy?
Yes, butter melting in a pan is a physical change. It absorbs heat energy to change from a solid to a liquid state.

What is the relationship between the heat of reaction and the chemical reaction?
The heat of reaction is the amount of heat released or absorbed during a chemical reaction. It is a measure of the energy change that occurs as reactants are converted into products. The relationship between the heat of reaction and the chemical reaction is that the heat of reaction indicates whether a reaction is exothermic (releases heat) or endothermic (absorbs heat).
What chemical reaction that absorbs heat called?
Endothermic reactionFor endothermic reactions Hfinal > Hinitial and DH is positive (+DH)It can be for example melting ice, or vaporising Rubbing Alcohol.---------Change of phases are not chemical reactions !
