(a) Explanation Given info: The initial temperature of the air is 18 o C , the initial volume of the air in the balloon is 1600 m 3 and the final temperature of the air is 65 o C . Write the expression of ideal gas equation. P V = n R T (1) Here, P is the pressure of the gas. V is the volume of the gas. n is the number of moles of the gas. R is the universal gas constant. T is the temperature of the gas. Rewrite the equation (1) for the initial state. P V 1 = n R T 1 (2) Here, V 1 is the initial volume of the gas. T 1 is the initial temperature of the gas. Rewrite the equation (1) for the final state. P V 2 = n R T 2 (3) Here, V 2 is the final volume of the gas. T 2 is the final temperature of the gas (b) To determine The work done by the balloon to expand against the atmospheric pressure.
