How many calories are required to raise the temperature of 105 g of water from 30.0°c to 70.0°c?

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
