During an experiment, an ideal gas is found to obey an additional law
VP2 = constant. The gas is initially at a temperature T and volumeV.When it expends to a volume 2V, what does new temperature become.
At what temperature is the rms velocity of hydrogen molecule equal to that of an oxygen
a 3cm cube of ironn has one face at 100oc and te other in a block of ice at 00c . if k of iron= 0.2 CGS units and L for ice is 80cal/gm, then the amount of ice that melts in 10 mins is [assume steady state heat transfer]
How can we get PV =NKBT . what is the value of KB?
Urgent reply needed plzz help my exams are in this week:-
Q1) The volume of an air bubble becomes 11 times on reaching the surface of water from the bottom of a lake . If the height of mercury in the barometer be 75 cm , then calculate the depth of the lake.density of water is 1.02 x 103 Ans:100m

at moment t=0 a particle of mass m starts moving due to a force F=J cos ut where j and u are constants. find the distance covered by the particle as a function of t.draw the approximate plot of this function
a narrow glass tube 80 cm long and opens at both the ends is half immersed in mercury now the top of the tube is closed and is taken out of mercury . a 20cm long mercury column remains in the tube . find atmospheric pressure??
plz gv a detailed explanation
a flask of volume 1*10^ -3 contains3.0*10^12 oxygen molecules at a certain temperature.the mass of one molecule of oxygen is 5.3*10^-26 kg and root mean square velocity of its molecule at same temperature is400 ms^-1.calculate the pressure of the oxygen gas in the flask.
i want derivation of cp and cv for monoatomic, diatomic, triatomic..... plz answer fast its urgent 2morrow is my exam..

The atmosphere contains 3 x 1025 molecules of air in one cubic meter and the mean speed of the molecules is 103 m s-1. ind their mean free path and from that calculate the number of collisions of a molecule with other molecules in 1sec.(i.e. collision frequency). (Take the diameter of air molecules to be 2 x 10 -10m).
Show that velocity of sound in air increases approximately by 0.61 m/sec for every 1 degree celsius rise in temperature
