The momentum of an object is defined as the product of its mass and the velocity with which it is moving.
The law of conservation of momentum states that the total momentum of a system remains conserved when the external force acting on it is equal to zero.
D. Exothermic, because energy is being absorbed from the surroundings
Explanation:
This is true about the Exothemic reaction due to the fact that, the reaction occurs outside the body. During this reaction, the energy being absorbed <em>from the surrounding environment will hit the body surface thereby creating the coldness due to the heat given out from the body being minimal.</em>
