Question

A jeweler is heating a bar if gold. It takes 7 joules of heat to raise temperture if the bar 1degrees celsuisThe initial temperture of the bar is 25degress celsuis. How many joules of heat would be required to raise temperture to 26 degrees

Answer 1

It would take + 7 joules if the starting temperature is = to 25 degrees Celsius. To raise the temperature by 1 it would take 7 joules.

1 degree = +7 joules

25 degrees = +175 Joules.

7 joules + 175 joules = 182 Joules

So the bar of gold will have to be 182 Joules to reach 26 degrees Celsius.
