The equation below can be used to find the specific heat capacity of a substance. Work out the specific heat capacity of a substance if it takes 5200J of energy to heat 2kg of it from 42°C to 47°C

Correct  c = 520 J/kg °K

Explanation:

The formula for calculating the amount of heat delivered to a given substance is:

Q = m · c · ΔT

the temperature difference is the same on the Kelvin scale and the Celsius scale

ΔT = Δt = 320 °K - 315 °K = 47 C° - 42 C° = 5 °K

c = Q / (m · ΔT) = 5,200 J / (2 kg · 5 °K) = 5,200 J / 10 kg °K = 520 J/kg °K

c = 520 J/kg °K

an unknown substance conducts heat well and could be metal

God is with you!!!

mass and volume are the answers you are looking for

it would be c. predictability
