Calculate the number of kJ of heat necessary to rise the temperature of 60.0 g of aluminum from `35^(@)C to 55^(@)C`. Molar heat capacity of aluminum is 24 J `mol^(-1)K^(-1)`.

Text Solution

Verified by Experts

q = msdT
q = heat liberated
m = mass of aluminum
s = molar heat capacity of aluminum
dT = change in temperature
`q= (60)/(27)xx24xx20=1.09 kJ.`
