Answer:
Answer in explanation
Explanation:
Water is mainly used as coolant in heating systems like hot-water radiators. The main function of water in such systems, is to absorb as much heat as possible, in order to decrease the temperature of the system and as a result cool it.
The specific heat capacity is the measure of heat energy that is required to raise the temperature of unit mass of a substance through 1 °C. In other words, specific heat capacity quantifies the amount of heat that can be stored by a unit mass of a substance having a degree rise in temperature.
Thus, the more specific heat a substance has, the more heat it can absorb from the hot system. Hence, the specific heat capacity of a coolant must be high.
<u>This is the reason why water, with its high specific heat capacity, is utilized for heating systems, such as radiators.</u>

Answer:
8 J
Explanation:
Given : Force = 2 N
Distance = 4m
Work done = force * distance
Work done = 2 * 4 = 8 J
