Interpretation: The direction of heat flow and type of process is to be described.
Concept Introduction : Heat flows when there is a temperature difference between two bodies. It flows from the hotter body to the colder body.
Endothermic process is one in which heat flows from the surroundings to the system, and the exothermic process is one in which heat flows from the system to the surroundings.
Answer to Problem 8LC
The direction of heat flow will be from blanket to body. The process is endothermic.
Explanation of Solution
The blanket is heated by electric power. The blanket is at a higher temperature than the body, the heat flow will be from the blanket to the body. Also, as heat flows from the surroundings to the system, the process will be endothermic in nature.
