Question

Assertion : Temperatures near the sea coast are moderate.

Reason : Water has a high thermal capacity.

(a) Both A and R are true and R is the correct explanation of A

(b) Both A and R are true but R is not correct explanation of A

(c) A is true but R is false

(d) A and R are false

Answer 1

Correct option (a) Both A and R are true and R is the correct explanation of A

Explanation :

Water has high specific heat or thermal capacity (mass x sp. heat). It cools slowly and heats up slowly and exchange of heat is large in each case. The area coast does not continue to be hot or cold. The temperature is therefore moderated.
