Question

Calculate the specific heat capacity of a substance if it takes 542000J of energy to heat up 1kg of it from 40 to 60°C

Answer 1

Answer:

27100 j/kg°C

Explanation:

542000=1×20×c

542000/20=c

27100=c

Answer 2

Answer: As we know that

Q = mc∆T

Where, Q = Heat supplied

m = Mass of substance

c = Specific heat &

∆T = Change in temperature

now putting values u will get

c = 27.1 J/(°C g)

please there may be a difference in the answer because I have used the gram as the unit of weight you can use kilogram instead.
