Chapter 2 - Study of Gas Laws Exercise 21
(b)The value of standard pressure is (i) 1 atm, (ii) 760 mm of Hg, (iii)76 cm of Hg, (iv)760 torr
(i) Absolute pressure (P),
(ii) Volume (V), and
(iii) Absolute temperature (T).
Chapter 2 - Study of Gas Laws Exercise 22
For a given mass of air at constant temperature, the following observations are made-
(i) The volume of air decreases with increasing pressure and vice versa.
(ii) The proportion by which the volume decreases or increases is the same by which the pressure increases or decreases.
(b) Pressure will be double.
(b) absolute zero
(c) absolute temperature
(d) the average kinetic energy
(b) At absolute zero temperature, volume of a gas would be reduced to zero. Theoretically,this is the lowest temperature that can be reached. At this temperature all molecular motions cease. Thus, practically this temperature is impossible to attain because on cooling gases liquefy and Charles' law is no more applicable.
(c) According to combined gas law equation, there is simultaneous effect of temperature and pressure changes on the volume of a given mass of a gas. So, when stating the volume of a gas, the pressure and temperature should also be given.
(b) False
(c) False
(d) False
(e) False
