 1)The specific gravity of CCl4 vapour at 273K and 76 cmHg in grams/litres ?

2)A monoatomic gas, a diatomic gas and a triatomic gas are mixed, taking one mole of each, the Cp/Cv for the mixture is ?

3)One mole of an ideal monoatomic gas is mixed with 1 mole of an ideal diatomic gas. The molar specific heat of the mixture at constant volume is ?

4)If the product of the gas constant R,i.e, 0.0821 lit atm/K/mole and NTP temperature in kelvin equals 22.4, the compressibility factor of the gas at 1 atm pressure is.. what temperature we shall take here, since they are telling NTP where T is 273K or 22.4K. am confused
 
5)The rms speed of N2 molecules in a gas sample can be changed by.
a)an increase in volume of the sample
b)mixing with Ar sample.
c)an increase in pressure on the gas
d)an increase in temperature.
in answers only option (d) is given correct, but rms speed is also directly proportional to pressure as well as volume, so won't it be changed by increasing the pressure & volume.

Please read forum rules.

For (1) I'll give you a hint. You are dealing with gas and the temperature, pressure and volume are given.

thanks a lot, I got the answer its 6.8709

@ Borek Sir, I have read the rules.

I think I made the mistake of posting it in Undergraduate Section because I am in class 11th now, so from next time I'll be posting all my doubts in High School Section.

@ Mitch Sir, From next time onwards whenever I'll post my doubts I'll show my working. Sorry for this time.

Anyways I got the answers.
