Question

What is the specific heat capacity of silver metal if 32.0 kg of the metal absorbs 55.0 J of heat and the temperature rises 21.0 C?

Answer 1

Answer:

Specific heat capacity of silver metal = 0.08184 J/kg°C

Explanation:

Given:

Mass of silver metal = 32 kg

Change in thermal energy = 55 J

Change in temperature = 21°C

Find:

Specific heat capacity of silver metal

Computation:

Using Specific heat capacity formula

C = ΔE / mΔT

where;

C = Specific heat capacity

ΔE = Change in thermal energy

m = Mass

ΔT = Change in temperature

C = (55) / (32)(21)

Specific heat capacity of silver metal = 55 / 672

Specific heat capacity of silver metal = 0.08184 J/kg°C
