Answer:

The change in temperature is 77.51 K.

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 [tex]0.129\ J/g{\cdot} K[/tex]. The heat supplied of released is given by :

[tex]Q=mc \Delta T[/tex]

[tex]\Delta T[/tex] is change in temperature

[tex]\Delta T=\dfrac{Q}{mc}\\\\\Delta T=\dfrac{1000}{100\times 0.129}\\\\\Delta T=77.51\ K[/tex]

So, the change in temperature is 77.51 K.
