Question 19

A student does an experiment to determine the specific heat capacity of a metal block.

She records the following measurements:

  • Energy supplied = 15 kJ
  • Initial temperature = 18 ∘C18\text{ }^\circ\text{C}18 ∘C
  • Final temperature = 58 ∘C58\text{ }^\circ\text{C}58 ∘C
  • Mass of metal block = 750 g

What is the specific heat capacity of the metal block?

A

5.0×10−4 J/(kg ∘C)5.0 \times 10^{-4}\text{ J}/(\text{kg }^\circ\text{C})5.0×10−4 J/(kg ∘C)

B

0.50 J/(kg ∘C)0.50\text{ J}/(\text{kg }^\circ\text{C})0.50 J/(kg ∘C)

C

350 J/(kg ∘C)350\text{ J}/(\text{kg }^\circ\text{C})350 J/(kg ∘C)

D

500 J/(kg ∘C)500\text{ J}/(\text{kg }^\circ\text{C})500 J/(kg ∘C)
