Question : 28
Match List I with List II and select the correct answer using the codes given below the lists:
List I | List II |
A. The coefficient of volume expansion at constant pressure | 1. Decrease in pressure |
B. At constant temperature, an increase in volume results in | 2. At all temperature |
C. An ideal gas obeys Boyle’s and Charle’s law | 3. Same for all gases |
D. A real gas behaves as an ideal gas at low pressure | 4. At high temperature |
a) A – 3, B – 1, C – 2, D – 4
b) A – 2, B – 3, C – 4, D – 1
c) A – 2, B – 1, C – 3, D – 4
d) A – 3, B – 4, C – 1, D – 2
Answer »Answer: (a)
(A) → 3 Cv = $1/{273}$ °C same for all gases
(B) → 1 PV = cos A ⇒ P ∝ $1/V$
(C) → 2 Ideal gas obeys gas law at each range of temperature.
(D) → 4 At high temperature, intermolecular forces become zero and so real gas behaves like an ideal gas.
Question : 29
Which of the following statements is/ are false about mode of heat transfer?
- In radiation, heat is transfered from one medium to another without affecting the intervening medium
- Radiation and convection are possible in vaccum while conduction requires material medium.
- Conduction is possible in solids while convection occurs in liquids and gases.
a) II only
b) I only
c) II and III
d) I, II and III
