Question

what mass in grams, of aluminum fins could 3088J of energy heat from 14.77 degrees C to 26.31 degrees C? Aluminum has a specific heat of 0.897/J (g degrees Celsius)?

Answer 1

298.32 grams

Step-by-step explanation:

Amount of energy required by known amount of a substance to raise its temperature by one degree is called specific heat capacity.

The equation used for this problem is as follow,

Q = m Cp ΔT ----- (1)

Where;

Q = Heat = 3088 J

m = mass = ??

Cp = Specific Heat Capacity = 0.897 J.g⁻¹.°C⁻¹

ΔT = Change in Temperature = 26.31 °C - 14.77 °C = 11.54 °C

Solving eq. 1 for m,

m = Q / Cp ΔT

Putting values,

m = 3088 J / (0.897 J.g⁻¹.°C⁻¹ × 11.54 °C)

m = 298.32 g
