The isotherms of a gas are shown below : Among the following, (i) At T 1 , the gas cannot be liquefied (ii) At point B , liquid starts to appear at T 2 (ii) T C is the highest temperature at which the gas can be liquefied (iv) At point A , a small increase in pressure condenses the whole system to a liquid The correct statements are :
Options
- Aonly (i) and (ii)
- Bonly (i), (iii) and (iv)
- Conly (ii), (iii) and (iv)
- D(i), (ii), (iii) and (iv)
Correct answer
D. (i), (ii), (iii) and (iv)
Step-by-step solution
Since T 1 > T C , the gas cannot be liquefied at T 1 , T C is the highest temperature at which the gas can be liquefied. At temperature T 2 , liquid starts to appear at point B , however a small increase in pressure at point A condenses the whole system to liquid.
