The temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.
The temperature change of a calorimeter can be calculated using the following expression:
E = mc∆T
Where;
400 = 10 × 4.18 × ∆T
400 = 41.8∆T
∆T = 400/41.8
∆T = 9.57°C
Therefore, the temperature change if 400 J of energy is added to 10 grams of water is 9.57°C.
