If 8162.7 J of heat are added to 39 g of water initially at
19°C,
(a) How much energy is this in calories?
(b) What is the final temperature of the water?
Homework Answers
a)
1 cal = 4.18 J
1 J = 1/ 4.18 cal
8162.7 J = 1952.8 cal
=====
b)
q = m C dT
8162. 7 = 39*10^-3* 4186* dT
T - 19 = 50
T = 69 C
======
Comment in case any doubt, will reply for sure.. Goodluck
