Answer:
Q = 5844.3 j
Explanation:
Given data:
Specific heat of copper = 0.42 j/g.°C
Mass of sample = 275 g
Initial temperature = 25.2°C
Final temperature = 75.8°C
Energy required = ?
Solution:
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 = 75.8°C - 25.2°C
ΔT = 50.6°C
Q = 275 g × 0.42 j/g.°C × 50.6°C
Q = 5844.3 j
