Answer:
c = 0.39 J/g.°C
Explanation:
Given data:
Energy required = 242.2 J
Mass of copper = 81.6 g
Initial temperature = 27.5°C
Final temperature = 35.2°C
Specific heat capacity of copper = ?
Solution:
Specific heat capacity:
It is the amount of heat required to raise the temperature of one gram of substance by one degree.
Formula:
Q = m.c. ΔT
Q = amount of heat absorbed or released
m = mass of given substance
c = specific heat capacity of substance
ΔT = change in temperature
ΔT = 35.2°C - 27.5°C
ΔT = 7.7°C
242.2 J = 81.6 g ×c × 7.7°C
242.2 J / 81.6 g = c × 7.7°C
c = 3 J/7.7g.°C
c = 0.39 J/g.°C
