प्रश्न
Is it possible to change the temperature and pressure of a fixed mass of a gas without changing its volume? Explain your answer.
उत्तर
No. it is not possible to change the temperature and pressure of a fixed mass of a gas without changing its volume because all the three variables are interrelated to each other by the gas equation as :
PV/T = K (constant) -----1)
Hence if we change any one or two of the variables in the above equation then automatically third variable also has to change to make equation 1 equal to a constant.
