Kinetic Theory Of Gases

Question 1

what to do if we have a container having some as stoppn suddenly and asked the change in temperature

Answer 1

equate 1/2Mv^2=3/2KT

Question 2

whats equated when two different type of agses under different circumstances are mixed

Answer 2

number of moles is equated

Question 3

A real gas beahves like an Ideal gas at

Answer 3

Low pressure and high temperature

Question 4

expansion of gas in vaccum(free expansion of a gas)
work done=?
Delta U=
DElta Q=
temperature will be varying/constant
is free expansion of gas an adiabatic process?

Answer 4

Work done=0
Delta U=0
DElta Q=0
temperature will be constant
no, free expansion is not an adiabatic process

Question 5

when the max height is asked for a molecule to achieve when a closed container is opened in vacuum

Answer 5

equate 3/2KT=mgh

Question 6

which speed to consider for calculating if it will escape a planet or not

Answer 6

most probable speed

Question 7

mean separation between molecules formula

Answer 7

Question 8

mean time between collisions =

and it’s proportional to

Answer 8

Question 9

in closed piston/cylinder with movable piston, if its adiabatic, temperature will remain same/change

Answer 9

remain same

Question 10

rate of evaporation or any such rate

what to find?

Answer 10

dm/dt

mass by time

Question 11

total kinetic energy of molecules

Answer 11
