Landfills

The landfill is a site used for the disposal of waste materials. The landfill is a solid waste facility that is often known as a dumping ground. The image below shows a landfill site in Hawaii. Landfilling is the most ancient and common method used for the disposal of waste. For the landfill, a deep trench is constructed in an isolated place away from the city. The trench for landfills is designed properly after analyzing the total population and the waste generation per capita. The waste is dumped into the trench and after every layer of waste, a layer of soil is spread on the top of it.

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?
