Find the specific heat of an unknown metal an initial temperature of 16.0 Celsius when 3500 joules to a 40.0g sample and the final temperature is 81.0 Celsius

Specific heat 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.
