Asked by henry

100.0g of 4.0c water is heated until its temperature is 37c. if the specific heat of water is 4.18 j/g c, calculate the amount of heat energy needed to cause this rise in temperature.
Answered by DrBob222
q = mass H2O x specific heat x (Tfinal-Tinitial)
YOu know mass, specific heat, Tfinal and Tinitial. Solve for q.

m = 100g
c = 4.18
∆T = 33°C

Q = mc∆T
Q = 100g * 4.18 * 33°C
= 13794J

Compare the energy needed to raise the temperature of 1kg of water from 20°C to 100°C and the energy needed to boil 1 kg of water at 100°C
