Laws of Equilibrium

A body is said to be in equilibrium if the system of forces acting on the body tends to keep the body at rest, in other words, there is no translation motion or net torque on the body. Under such conditions, the equilibrium conditions are to be applied to analyze the condition. The branch of mechanics that deals with this condition is known as 'statics'. Under equilibrium, there are no net forces on the body.

The rate at which the temperature of an object is related to the difference between the temperature of the object and the temperature of the surrounding. A metal was chilled at roughly 0°C. It was then left in a room where the temperature is 30°C. In 10 minutes the metal became 10°C. It was left again for another 10 minutes, and then heated to a container with boiling water at 100°C. Assuming the rate of proportionality is constant. What will be the final temperature of the metal, in °C, after boiling it in 10 minutes?
