Question

A 200.0 g copper block absorbs 2.34 × 10^3 J of heat to raise its temperature by 30.0 K. What is the specific heat of copper? Please show your work/all the steps.

Answer 1

Answer: 0.39 Jg/K

Explanation:

$Q= m\times c\times \Delta T$

Q = heat gained = $2.34\times 10^{3}Joules$

m = mass of the substance = 200 g

c = heat capacity of copper = ? J/g ° C      

$\Delta T={\text{Change in temperature}}=30K$  

$2.34\times 10^{3}=200g\times cJ/gK\times 30K$

$c= 0.39Jg/K$

Thus specific heat of copper is 0.39 Jg/K.

Answer 2

Specific heat = Heat / (mass x change in temperature)

specific heat= 2.34 x 10^3 / 200 x 30

specific heat = 2,340 / 6,000

Specific Heat= 0.39
