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

215 [C°].

Step-by-step 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=(Q)/(cm)+t_0;`

3) according to the formula above:

`t=(4500)/(0.39*100)+100=215.`
