Question

The specific heat of copper is 0.42J/g°C. How much energy is required to heat a 275g sample of copper from 25.2°C to 75.8°C?

Answer 1

Q = 5844.3 j

Step-by-step 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
