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?
1 answer:
Answer:
1.18010256J/Kg°C
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
