Question

The melting point of silver is 962 °C. If its latent heat of fusion is 105 x 103 J/kg. Calculate the amount of heat required to raise the temperature of 2000 g of silver from 24 °C to 1000 °C. (Assuming SHC of silver as 0.240 J/g °C​

Answer 1

Answer:

represents the amount of heat required to change a unit mass of a substance by one degree Celsius. This is expressed mathematically as:

q

=

m

⋅

c

⋅

Δ

T

, where

q

- the amount of heat supplied;

m

- the mass of the substance;

c

- the respective substance's specific heat;

Δ

T

- the change in temperature.

So, if we want to determine the units for specific heat, we'll just isolate the term in the above formula to get

c

=

q

m

⋅

Δ

T

. Since heat is measured in Joules (J), mass in grams (g), and temperature in degree Celsius (

C

), we can determine that

c

=

J

g

⋅

∘

C

.

Therefore, specific heat is measured in Joules per g times degree Celsius.
