1. ∆T = 0
2. ∆P = 0
3. q = 0
4. w = 0
The enthalpy of formation of all elements in their standard state is-

Calculate the amount of heat required to raise the temperature of 60.0 g of aluminium from 35°C to 55°C.
(Molar heat capacity of Al = 24 J mol⁻¹ K⁻¹; molar mass of Al = 27 g mol⁻¹)
| 1. | \(1 . 07\) \(J\) | 2. | \(1 . 07\) \(kJ\) |
| 3. | \(106 . 7\) \(kJ\) | 4. | \(100 . 7\) \(kJ\) |
