To heat 1g of water by 1c requires

a. 1 volt

b. 1 calorie

c. 1 joule

d. 1 watt

B) 1 Calorie

Explanation: The heat required to raise the temperature of 1 gram of a substance by 1 degree C is known as its specific heat capacity.

Specific heat capacity of water is and we know that, 4.184 Joule = 1 Calorie

So, specific heat capacity of water is and hence the correct choice is B.

the positions which points up in upward carbon and down in downward carbon are axial

and vice versa holds true for equatorial positions

so the correct answer with labelled diagram will be
