Concept:Newton's law of cooling states that the rate of heat loss is proportional to the temperature difference between the body and its surroundings.Explanation:The rate of loss of heat is written as: $$\frac{dQ}{dt} \propto (T - T_0)$$ where $T$ is the temperature of the body and $T_0$ is the temperature of the surroundings.Therefore, it depends on the difference in temperature between the body and its surroundings.Answer:C. difference in temperature between the body and its surroundings
