Question

3. How much Heat must be added to a 10 gram sample of Gold to increase itstemperature by 5 C. The Specific Heat of Gold is 0.13 J/g C

Answer 1

6.5Joules

Explanations:

The formula for calculating the amount of heat that must be added is expressed as:

`Q=mc\triangle t`

where:

• m is the ,mass ,of the object

,

• c is the s,pecific heat capacity

,

• △t is the ,change in temperature

Given the following parameters

m = 10grams

c = 0.13 J/g C

△t = 5 C

Substitute the given parameters into the formula

`\begin{gathered} Q=10\cancel{g}*\frac{0.13J}{\cancel{g}^\cancel{^0C}}*5\cancel{^0C}^ \\ Q=10*0.13J*5 \\ Q=1.3*5 \\ Q=6.5Joules \end{gathered}`

This shows that 6.5Joules of heat must be added to a 10 gram sample of Gold to increase its temperature by 5 C.
