A branch of science wherein it studies the transfer of energy from one to another
Therma-dynamics
A system where it doesn’t absorb any energy or no interaction of energy and the matter will retain
Isolated system
A system where the matter doesn’t actually interact with the surrounding although there is an exchange of energy
Closed system
A system where energy can be exchange, so as the matter with its surrounding
Open system
What type of Therma-dynamics system is Earth?
Closed system, since some of the Heat that enters Earth can bounce back
