Suppose that the pressure of an ideal gas mixture remains constant at 1800 pa (1 pa = 1n/m2) and the temperature is increased from 250k to 750k. a. if the original volume of the gas was 0.15 m3, what is the final volume? b. what is the change in volume for this process? c. how much work does the gas do on the surroundings during the expansion? d. if the initial volume was 0.24m3 and the same tempera- ture change occurred, would the work done be the same as in the first case? show by repeating the steps of the first three parts. e. is the same amount of gas involved in these two situa- tions? explain.
