Question

According to kinetic theory of gasses at Zero kelvin

a) Pressure of ideal gas is zero

b) Volume of ideal gas is zero

c) Internal energy of ideal gas is zero

d) Matter exists in gaseous state only

• A. a & d are true
• B. a,b & d are true
• C. a,b & c are true
• D. All are true

Answer 1

Answer: (C)

a,b & c are true

Since at zero Kelvin it is not true that matter exist in gaseous state only.
Where as from PV=nRT
P=0
V=0
KE=3RT/2=0; since T=0 K
Therefore, option(C) is true.
