In an experiment to find the specific heat capacity of a metal, it is found that 5200 J is needed to raise the temperature of a 2kg block by 20 °C

What value for the specific heat capacity is given by these results?
A 130 J/(kg C)
B 520J/(kg C)
С 52 000 J/(kg°C)
D 104 000 J/(kg°C)

Answer:

A. 130J / kg°C

Explanation:

Amount of heat (Q) = 5200 J

mass (m) = 2 kg

temperature (dt) = 20°C

specific heat capacity (S) = ?

We know

Q = msdt

5200 = 2 * s * 20

s = 5200 / 40

s = 130 J /kg °C

Hope it will help :)
