For a constant volume gas thermometer, one should fill the gas at

1.  low temperature and low pressure

2.  low temperature and high pressure

3.  high temperature and low pressure

4.  high temperature and high pressure.

A gas behaves more closely as an ideal gas at:

The following figure shows graphs of pressure versus density for an ideal gas at two temperatures \(T_1\) and \(T_2.\)

         
Then:

The pressure of a gas kept in an isothermal container is 200 kPa. If half the gas is removed from it, the pressure will be

1.  100 kPa

2.  200 kPa

3.  400 kPa

4.  800 kPa.

The process on an ideal gas as shown in the figure given below is:
             

1. isothermal
2. isobaric
3. isochoric
4. none of these

Consider the quantity  \(MkT \over pV\) of an ideal gas where M is the mass of the gas. It depends on the

(a) temperature of the gas

(b) volume of the gas

(c) pressure of the gas

(d) nature of the gas

Chooose the correct option 

1.  (a), (b) 

2. (b) , (c) 

3.  (d) only

4. (a) (d)
