Question

If 4.5 kJ of energy is added to 100 g of copper at 100ºC, what is the final temperature in degrees Celsius?

Answer 1

Answer:

215 [C°].

Explanation:

1) if the given energy is Q, the initial temperature is t₀, the final temperature is t, then

2) Q=cm(t-t₀);

$t=\frac{Q}{cm}+t_0;$

3) according to the formula above:

$t=\frac{4500}{0.39*100}+100=215.$
