That's called "<em>Geothermal</em>" energy.
"Geo ..." always means something about the Earth.
"Thermal ..." always means something about heat.
Geothermal energy is used in places where there's a lot of heat that's not too far under the ground, like in places above ancient volcanos.
The system is built with pipes running deep down into the ground and then back up again, and then running water is pumped through the pipes. The water picks up heat from down under and brings the heat up to the surface, where it can be used to heat homes and buildings, and turn steam turbines to generate electricity.
Geothermal is the MAIN source of energy in Iceland.
I believe we live in the Cenozoic era
We live in the Holocene Epoch, of the Quaternary Period, in the Cenozoic Era (of the Phanerozoic Eon).
Answer:
586 K
Explanation:
Let P is the initial pressure.
Initial temperature, T₁ = 20°C = 293 K
Final pressure, P₂ = 2P
We need to find the final temperature of the gas.
The relation between the pressure and the temperature is as follows

Put all the values,

So, the final temperature of the gas is 586 K.

Answer:
8W
Explanation:
Given parameters:
Distance covered = 20m
Work done = 120J
Time = 15s
Unknown:
How much power does the Ox exerts = ?
Solution:
Power is the rate at which work is being done
Power =
Power exerted by ox =
= 8W
