A 0.190 kg piece of copper is heated and fashioned into a bracelet. The amount of energy transferred as heat to the copper is 6.62 x 10^4 J. If the specific heat of copper is 387 J/kg x °C, what is the change in temp of the copper?

To find the change in temperature of the copper, we can use the formula:

Energy transferred = mass × specific heat × change in temperature

We are given:
Mass of copper = 0.190 kg
Energy transferred as heat = 6.62 x 10^4 J
Specific heat of copper = 387 J/kg x °C

Substituting the given values into the formula, we can solve for the change in temperature:

6.62 x 10^4 J = 0.190 kg × 387 J/kg x °C × change in temperature

Dividing both sides of the equation by (0.190 kg × 387 J/kg x °C):

change in temperature = (6.62 x 10^4 J) / (0.190 kg × 387 J/kg x °C)

change in temperature ≈ 90.5 °C

Therefore, the change in temperature of the copper is approximately 90.5°C.

To find the change in temperature of the copper, we can use the formula:

Q = mcΔT

Where:
Q is the amount of energy transferred as heat (6.62 x 10^4 J)
m is the mass of the copper (0.190 kg)
c is the specific heat of copper (387 J/kg x °C)
ΔT is the change in temperature we want to find.

Now, rearranging the formula to solve for ΔT:

ΔT = Q / (mc)

Substituting the given values:

ΔT = (6.62 x 10^4 J) / (0.190 kg * 387 J/kg x °C)

Calculating:

ΔT = (6.62 x 10^4 J) / (73.53 J/°C)

ΔT ≈ 898.9 °C

Therefore, the change in temperature of the copper is approximately 898.9 °C.

Heat= mass*specificheat*changetemp

solve for change in temp.
