a 0.6 piece of copper is heated and fashioned into a bracelet The amount of energy transferred by heat to the copper is 62,100 J if the specific heat of copper is 390 J/g .c what is the change of the copper temperature.



Answer :

The change of the copper temperature if a 0.6g piece of copper is heated and fashioned into a bracelet with 62,100 J amount of energy transferred is 265.4°C.

How to calculate change in temperature?

The change in temperature of a metallic substance in a calorimetry experiment can be calculated using the following formula:

Q = mc∆T

Where;

  • Q = quantity of heat absorbed or released
  • m = mass of copper
  • ∆T = change in temperature
  • c = specific heat capacity

According to this question, a 0.6g piece of copper is heated and fashioned into a bracelet The amount of energy transferred by heat to the copper is 62,100 J.

62100 = 0.6 × 390 × ∆T

62100 = 234∆T

∆T = 62100/234

∆T = 265.4°C

Therefore, the change of the copper temperature if a 0.6g piece of copper is heated and fashioned into a bracelet with 62,100 J amount of energy transferred is 265.4°C.
