Answer: Rainfall and temperature can affect the rate in which rocks weather. High temperatures = more rainfall increasing the rate of chemical weathering. Rocks in tropical regions exposed to a lot of rainfall and hot temperatures weather faster than similar rocks in cold, dry climates.

Explanation:
First law of thermodynamics
It is also known as energy conservation law.It state that net work in a cyclic process is equal to net heat in that cycle.
From first law
Q=ΔU + W
ΔU = Q - W
ΔU is the change in internal energy of gas.
Q is heat transfer from the system or to the system.
W is the work done by the system or on the system.
If work done on the system then it will be taken as positive and If work done by the system then it will be taken as negative.
If heat taken by system it will taken as positive and If heat rejected by system it will taken as negative.
So Q will be positive if system gains heat and work will be positive if work is done on the system.
