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,

A chemical change can be caused by a reaction. It an element or compound reacts with another, it is known as a chemical change.
Chemical
Change in temperature is not a chemical change rather it is a physical change because it does not cause any change in composition or chemical properties of matter.
It is physical change
Signs of a chemical change include the formation of a precipitate, a color change, the release of gas (bubbles), and a temperature change (exothermic or endothermic). These changes indicate that new substances are being formed with different chemical properties than the original substances.
No, a catalyst does not change the overall energy of a reaction. It only lowers the activation energy required for the reaction to occur. Therefore, a catalyst cannot change an endothermic reaction into an exothermic one.
Cooking food can cause chemical Changes
Yes, it does.
No, flattening is a physical change, not a chemical change. A chemical change involves a change in the chemical composition of a substance, whereas flattening simply changes the shape or appearance of the object.
