Gold has a specific heat of 126 J/(kg ! K). A sculptor increased the
temperature of a 0.5 kg block of gold by 10°C. How much energy did
the sculptor add to the gold?

Energy Change= Mass X Specific Heat X Temperature Change

126 times .5 = 63.

63 times 10= 630

630 joules

Answer:

630 J

Explanation :

The formula for the heat required is

q = mCΔT

q = 0.5 × 126 × 10

q = 630 J
