Question

0.5 kg of copper needs 1905J of heat to raise it's temperature through 10°C . calculate the heat capacity of the sample​

Answer 1

Explanation:

Q = m x s x∆T

1905 = 0.5 x s x 10 = 5 x s

s = 1905/5 = 381 J/(Kg c⁰)

s = specific heat capacity

Answer 2

Answer:

The specific heat capacity is 381 J/Kg

Explanation:

STEP 1:

Given that

mass of copper = 0.5 Kg

The amount of heat required to raise 10°c is = 1905 J

Heat capacity =?

STEP 2 :

The specific heat is given by

Q= m*s*delta(T)

where Q is the heat

m is the mass

s is the specific heat capacity

T is the temperature

STEP 3:

Therefore s = Q / m* delta(T)

                   = 1905 / 0.5*10

                   = 1905 / 5

                   = 381

Thus the specific heat capacity of the sample is 381 J/Kg.
