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?

Why did the copper go to the gym? Because it wanted to get ripped! But I guess it also wanted to burn some energy, because this is a heat transfer problem.
To find the change in temperature, we can use the equation:
Q = m * c * ΔT
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), and
ΔT is the change in temperature (what we're trying to find).
Let's rearrange the formula to solve for ΔT:
ΔT = Q / (m * c)
Now let's plug in the values:
ΔT = (6.62 x 10^4 J) / (0.190 kg * 387 J/kg x °C)
Calculating the change in temperature:
ΔT ≈ 90.7 °C
So the change in temperature of the copper is approximately 90.7 °C. But remember, this is just a rough estimate, so don't copper too much!
To find the change in temperature of the copper, we can use the formula:
Q = m * c * ΔT
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),
and ΔT is the change in temperature of the copper (what we're trying to find).
Rearranging the formula to solve for ΔT:
ΔT = Q / (m * c)
Plugging in the given values:
ΔT = (6.62 x 10^4 J) / (0.190 kg * 387 J/kg x °C)
ΔT ≈ 89.3 °C
Therefore, the change in temperature of the copper is approximately 89.3 °C.
To find the change in temperature of the copper, you can use the formula:
Q = mcΔT
Where:
Q is the amount of heat transferred to the copper (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
Rearranging the formula, we can 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 this gives us:
ΔT = 9.31 °C
Therefore, the change in temperature of the copper is 9.31 °C.
