Question

A sample of 250 g of water are heated from 40°C to 121°C, calculate the amount of heat energy absorbed.

552,000 Joules
100,416 Joules
638, 555 Joules
73,885 Joules

Answer 1

the anwser isn't in the choices

Step-by-step explanation:

H=MC(change of temp.)

M=mass of water=250g

C=specific heat of water = 4.186 j/g

change in temperature is 121-40= 81

H= 250x4.186x81=84766.5J
