An endothermic reaction needs energy to proceed, such energy is usually taken from the environment surrounding the reaction. In the typical case this energy is expressed as heat. Heat is an state of atomic activity, that energy is transferred to an ENDOthermic reaction so the initial threshold of reaction is overcome and the final reaction can occur.

Answer: 1. For a endothermic reaction , energy is absorbed

2. The temperature recorded by a thermometer in an endothermic reaction would be reduced.

Explanation:

Endothermic reactions are defined as the reactions in which energy of the product is greater than the energy of the reactants. The total energy is absorbed in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants come out to be positive. The temperature of the surroundings will decrease.

Exothermic reactions are defined as the reactions in which energy of the product is lesser than the energy of the reactants. The total energy is released in the form of heat and $\Delta H$ which is difference between energy of products and energy of reactants comes out to be negative.The temperature of the surroundings will increase.
