Answer:
146.25 J heat is require to cause the change of 15 °C.
Explanation:
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 = heat or energy in joule
m = mass of substance
c = specific heat of substance
ΔT = change in temperature
Given data:
Mass of copper = 25 g
Temperature change =ΔT= 15 °C
Specific heat of copper = 0.39 J/g.°C
Energy or joules require to increase the temperature Q = ?
Solution:
Q = m × c × ΔT
Q = 25 g × 0.39 J/g .°C × 15 °C
Q = 146.25 J
