Hydrogen Energy

Energy is a quantity that cannot be defined, its existence can only be felt. In simple language, if a system possesses energy, it can do a specific kind of work. There are many forms of energy sources which people can use to obtain work. Solar energy, tidal energy, hydroelectric energy, geothermal energy, wind energy are some of the renewable energy sources which are primarily used for the production of electricity.

Question

An object was left in a room of unknown surrounding temperature. The temperature of the object was
summarized below with respect to the time t (in minutes) the object was initially observed. Predict and
complete the information, i.e. determine the temperature in Celsius when t= 30 minutes. Put your answer
accurate up to four decimal places.
When t= 0, the temperature of the object is 30 degrees Celsius.
• When t= 10 minutes, the temperature of the object is 32 degrees Celsius.
• When t= 20 minutes, the temperature of the object is 33.6 degrees Celsius.
• When t= 30 minutes, the temperature of the object is unknown.
Assume the system obeys Newton's Law of Cooling and the surrounding temperature of the room did not
change.
