A sample of aluminum (c = 0.900 J/g°C) is heated from 20.8°C to 38.7 °C using 3,750 J of energy. What is the mass of the aluminum sample?
Expert Solution
Given
* Specific heat capacity of aluminium ;
C = 0.900 J/g°C
* ∆T = change in temperature = T2 - T1
T2 = 38.7 °C ( Final temperature )
T1 = 20.8°C ( initial Temperature )
∆T = 38.7 °C - 20.8°C
∆T = 17.9 °c
Q = heat absorbed = 3,750 J
M = mass of aluminium sample
