The two sources of heat in the earth's interior are-
A. The leftover heat from formation and radioactive decay
Explanation:
The leftover heat from the time when the planet was formed, which has not yet been lost, is a source of internal heating of the earth. There are various radioactive elements present deep inside the earth and they are decaying slowly and gradually and emit heat into the earth's interior.
Answer:
b. The overall amount of energy in the bowl will neither increase nor decrease.
c. The ice cream will increase in energy.
Explanation:
b. The total amount of energy in the container will not increase or decrease. Since the energy is transferred from one element to another, the energy that dissipates is negligible.
In this case the energy of the pie is transferred to the ice cream, melting it.
c. The ice cream will increase in energy. As the heat is transferred from the pie to the ice cream. the movement between the particles of the ice cream increases, increasing its kinetic energy
5 grams will be left. After the first 1000 years, there will be half of 20 left, or 10. After 2000 years, half of 10 will remain, which is 5.
