4. What is the specific heat of copper if it took 57.8 J of heat energy added to 10 grams to
produce a 15°C temperature change?

Specific heat capacity of copper is 0.385 J/g.°C

Explanation:

Given data:

Specific heat capacity of copper = ?

Heat absorbed by copper = 57.8 J

Mass of copper = 10 g

Temperature changes = 15°C

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

by putting values

57.8 J = 10 g × c × 15°C

57.8 J = 150 g.°C × c

c = 57.8 J / 150 g.°C

c = 0.385 J/g.°C

Specific heat capacity:

It is the amount of heat required to raise the temperature of one gram of substance by one degree.

Specific heat capacity of copper is 0.385 J/g.°C.
