How much heat must be added to a 4.33 g piece of aluminum to raise its temperature from 22.00 ° C to 27.00 ° C?
Specific Heat(Al) = 0.900 J/g × K

Question

Quizplus · Accepted Answer

To calculate the amount of heat required, we use the equation Q = m*c*(ΔT), where Q is the heat required, m is the mass of the substance, c is the specific heat capacity, and ΔT is the change in temperature.
Substituting the given values, we get:
Q = 4.33g * 0.900J/g*K * (27.00°C - 22.00°C) = 19.5J
Therefore, the amount of heat required to raise the temperature of the aluminum piece is 19.5 J. The correct choice is A.
