Answer to Question #257701 in General Chemistry for l jack

Question

How many joules are absorbed as the temperature of 15.0 grams of aluminum is heated from 20.0^oC to 60.0^oC?

Answer 1

$Q = mcΔT \\ ΔT = 60.0-20.0 = 40.0 \\ m = 15.0 \;g \\ c_{Al} = 0.900 \;J/g \cdot C \\ Q = 15.0 \times 0.900 \times 40.0 = 540 \;J$
