Can we define the temperature of(A)vacuum,(B)a single molecule?

Cooking gas container are kept in a lorry moving with uniform speed. The temperature of the gas molecules inside will

Acceleration is defined as the rate of change of velocity. Suppose we call the rate of change of acceleration as SLAP ? (i) What is the unit of SLAP . (ii) How can we calculate instantaneous SLAP ?

Two equal resistance at 0^(@)C with temperature coefficient of resistance alpha_(1) and alpha_(2) joined in series act as a single resistance in a circuit the temperature coefficient of their single resistance will be

Boiling point of water is defined as the temperature at which:

Statement-1 : At low pressure and high temperature real gas approaches the ideal gas behaviour. and Statement-2 : At low prossure and high temperature the molecules are negligible.

How can we determine whether the object is in rest or not?

The molecules of a gas A travel four times faster than the molecules of gas B at the same temperature. The ratio of molecular weight (M_A // M_B) will be

Three closed vessels A, B and C are at the same temperature T and contain gases which obey the Maxwellian distribution of velocities. Vessel A contains only O_(2), B only N_(2) and C a mixture of equal quantities of O_(2) and N_(2) . If the average speed of the O_(2) molecules in vessel A is V_(1) , that of the N_(2) molecules in vessel B is V_(2) , the average speed of the O_(2) molecules in vessel C is (where M is the mass of an oxygen molecules)
