The specific heat(c) of copper is 0.39 J/g °C. What is the temperature
change(At) when 100 Joules of heat(Q) is added to 20 grams?

The temperature change (∆T) of the copper when 100 Joules of heat is added to 20 grams is 12.82°C

HOW TO CALCULATE TEMPERATURE CHANGE:

The temperature change (∆T) of copper metal can be calculated using the following formula:Q = m × c × ∆T

Where;

Q = quantity of heat absorbed or released (J)m = mass of copper (g)c = specific heat capacity (J/g°c)∆T = temperature change (°C)According to this question, 100 Joules of heat is added to 20 grams of copper. The temperature change is calculated as follows:

100 = 20 × 0.39 × ∆T

100 = 7.8∆T

∆T = 100 ÷ 7.8

∆T = 12.82°C

Therefore, the temperature change (∆T) of the copper when 100 Joules of heat is added to 20 grams is 12.82°C
