Question

newtons law of cooling

Answer 1

Newton's law of cooling states that the rate of heat loss of a body is proportional to the difference in temperatures between the body and its surroundings. As such, it is equivalent to a statement that the heat transfer coefficient, which mediates between heat losses and temperature differences, is a constant.

Answer 2

Newton's law of cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the ambient temperature (i.e. the temperature of its surroundings).

Newton's Law makes a statement about an instantaneous rate of change of the temperature.

We will see that when we translate this verbal statement into a differential equation, we arrive at a differential equation.

The solution to this equation will then be a function that tracks the complete record of the temperature over time.
