Final answer:
To find the heat absorbed by a piece of aluminum, multiply the mass by the specific heat and the change in temperature. The 49.1 g of aluminum absorbs approximately 2.01 kJ when its temperature is raised from 23.0 C to 67.0 C.
Step-by-step explanation:
To calculate the quantity of heat absorbed by the piece of aluminum, we use the equation Q = mcΔT, where Q is the quantity of heat, m is the mass, c is the specific heat, and ΔT is the change in temperature.
Given that the mass of the aluminum is 49.1 g, the specific heat is 0.930 J/g°C, and the change in temperature is 67.0°C - 23.0°C = 44.0°C, we can substitute these values into the equation.
Q = (49.1 g)(0.930 J/g°C)(44.0°C) = 2025 J.
