1.	Taking the volume of hydrogen as 5000/7/ cm cube what change must be made in kelvin (Absolute. Temperature )to return the volume to 25000 cm cube pressure remaining constant.
Answer» GIVEN, V1 =2500 cm3 P1 =760mm [At S.T.P] It is said that Hydrogen is subjected to 2.5 times increase in pressure. Thus final pressure , P2 of the GAS is = 2.5 x P1 = 2.5 x 760 P2 = 1900 mm We have to find out V2 [final volume] which the gas occupies From Boyle's Law, At CONSTANT TEMPERATURE P1V1 = P2V2 Thus , V2 = P1V1P2 V2 = 2500×7601900 V2 = 1000cm3 Hope this information will clear your doubts about the topic.
