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

Answer:

                     298.32 grams

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
