There number of calories that are required to raise the temperature of 105 g of water from 30.0 c to 70.0 c is calculated as follows

Q(heat)= mass(m) x specific heat capacity of water ( 1 cal/g/c) x delta T ( change in temperature

delta T = 70.0- 30.0= 40.0 c

Q= 105 g x 1 cal/g/c x 40 c = 4200 calories is needed to raise temperature of water from 30 c to 70 c
