Pooja needs 15 kg water at 38°C,water is 20°C. Calculate heat ?


1 Answer


Given, 

mass of water m = 15 kg 

difference in temperature dt = 38-20

= 18°C

Specific heat capacity of water s = 4200 J/kg°C

Amount of heat Q= ? 

we have, 

Q=msdt 

Q= 15 * 4200 * 18 

Q = 113400 J

Q = 1.134 * 10 J
