Answer

a-Weight is the measure of how much force gravity puts on an object’s mass. An example of this is the weight we measure when we stand on a scale: the result will change depending on the greatness of the gravity force. b-Potential energy is mechanical or stored energy from an object that comes from a number of factors: internal stress, position in relation to another object, electrical charge and so on. An example of this is the mechanical energy stored inside a coiled spring. c-Temperature is the propriety of matter which reflects the quantity of motion of its particles. It is the comparative measure of how hot or cold an object is. An example can be the temperature of a solution. d-An endothermic reaction is a reaction that absorbs heat from its surroundings. An example of this is the reaction you obtain when you make water react with potassium chloride. e-An extensive propriety is a propriety that changes as the amount of matter changes, such are mass and volume.
