Final answer:
To determine the heat required to raise the temperature of aluminum, multiply the mass, specific heat capacity, and temperature change. For 100 g of aluminum and a 10°C increase, using the specific heat of 0.21 cal/g°C, the heat required is 210 calories.
Step-by-step explanation:
To calculate the amount of heat required to raise the temperature of a substance, you can use the formula Q = mcΔT, where Q is the heat added, m is the mass of the substance, c is the specific heat capacity of the substance, and ΔT is the change in temperature.
In this case, the student needs to find out how much heat is required to raise the temperature of 100.0 g of aluminum by 10.0°C with a specific heat capacity of 0.21 cal/g°C. Using the heat formula, we calculate the heat needed as follows:
Q = m c ΔT = (100.0 g) * (0.21 cal/g°C) * (10.0°C) = 210 calories.
Therefore, the correct answer is B. 210 calories.
