5.] One kg of air at a temperature of 20°C is heated to a temperature of 60°C. Find the heat supplied to
air when heated at constant pressure. The specific heat for air at constant pressure = 1 kJ/kg K.

Answer:
Actually Welcome to the Concept of the Thermodynamics.
Here, we simply aaplya the formula for the heat energy gained by a gas due to change in the temperature.
Q = mc∆T
here, Q = heat energy, m = mass in kg, c = specific heat capacity and ∆T = change in temperature in K.
hence, 20° C = 293 K and 60° C = 333 K
so, we get as,
Q = (1 kg) (1 KJ / Kg K)(333 K - 293 K)
Q= (1)(1000 J/ Kg K)(40)
Q = (40,000 ) Joules
hence, the heat gained is => Q = 40 KJ
