  • question_answer 1)
      The variation of pressure with volume of the gas at different temperatures can be graphically represented as shown in figure   On the basis of this graph answer the following questions : (i) How will the volume of a gas change if its pressure is increased at constant temperature? (ii) At a constant pressure, how will the volume of a gas change if the temperature is increased from 200 K to 400 K?

    Answer:

      (i) Volume of a gas will decrease if the pressure is increase at constant temperature. It is evident from the graph. The graph is in accordance with Boyle's law. (ii) On increasing the temperature, volume of gas will increase at constant pressure.
