Question

A 150 g ceramic serving bowl is warmed 52.0°C when it absorbs 2.2 kcal of heat from a serving of hot food. What is the specific heat of the china dish?

Answer 1

1.18010256J/Kg°C

Step-by-step explanation:

The quantity of heat energy is expressed as:

Q = mct

c is the specific heat capacity

t is change in temperature

Q = 4.184×2.2

Q = 9.2048Joules

m = 150g = 0.15kg

t = 52°C

Substitute and get c

9.2048 = 0.15c(52)

9.2048 = 7.8c

c = 9.2048/7.8

c = 1.18010256

Hence the specific heat capacity of the dish is 1.18010256J/Kg°C
