Final answer:
The amount of heat energy required to raise the temperature of 2 grams of water from 10°C to 15°C with a heat capacity of 10 J/g°C is calculated using the formula q = m × c × ΔT, giving a result of 100 J.
Step-by-step explanation:
The question asks about the amount of heat energy required to raise the temperature of 2 grams of water from 10°C to 15°C, given a heat capacity of 10 J/g°C. To calculate the heat energy (q), you use the formula q = m × c × ΔT, where m is mass, c is specific heat capacity, and ΔT is the change in temperature. Plugging in the given values:
q = 2 g × 10 J/g°C × (15°C - 10°C)
q = 2 g × 10 J/g°C × 5°C
q = 100 J
Therefore, the correct answer is [d] 100 J. This is the amount of heat energy added to increase the temperature of 2 grams of water by 5°C.
