1

What is the formula of linear expansion ?

Δl=lαΔt

2

What is the formula of volume expansion ?

Δv=vγΔt
For isotopic medium ,
γ=3α

3

What is the change in density due to thermal expansion ?

p'=p(1-γΔ#)
With increase in temperature , density should decrease.

4

What is the change in time period of pendulum due to thermal expansion ?

ΔT=1/2TαΔ#

5

What is the degree of freedom for monoatomic gas, diatomic gas , and for nonlinear polyatomic gases ?

f=3 for monoatomic gases.
f=5 for diatomic gases.
f=6 for nonlinear polyatomic gases.

6

What is the translational degree of freedom for any type of gas ?

Translational degree of freedom for any type of as is three.

7

What is the formula for total energy U of a gas ?

U= (nf)/2RT.
n= total number of gram moles.
