Question

Determine the temperature change when a 100. g block of gold is supplied with 1.00 x 103 J of heat.

Answer 1

The change in temperature is 77.51 K.

Step-by-step explanation:

We have,

Mass of gold, m = 100 g

Heat supplied, Q = 1000 J

It is required to find the temperature change when 100 block of gold is supplied with 1000 J of heat.

The specific heat of gold is
`0.129\ J/g{\cdot} K`. The heat supplied of released is given by :

`Q=mc \Delta T`

`\Delta T` is change in temperature

`\Delta T=(Q)/(mc)\\\\\Delta T=(1000)/(100* 0.129)\\\\\Delta T=77.51\ K`

So, the change in temperature is 77.51 K.
