The temperature at which the tungsten filament of 12v and 36w lamp operates is 1730^0c. if the temperature coefficient of resistance of tungsten is 6 x 10^-3/k, find the resistance of the lamp at a room temperature of 20^0c

The temperature(T) of an ideal gas varies with it's volume (V) as T=-aV ^ 3+bV^2.where 'a' and 'b' are positive constant s.the maximum pressure of gas during this process is.

A closed cylinder vessel contain N moles of an ideal diatomic gas at at constant temperature T.on supplying heat,temperature remains same but 'n' moles get dissociated into atoms.the heat supplied is....

To an ideal tri atomic gas 800cal heat energy is supplied at constant pressure.if vibrational mode is neglected, then energy used by as in work done against surrounding is
A) 200cal. B) 300cal. C) 400cal. D) 60cal

a sample neon gas occupies a volume of 2.8L at 1.8atm. what will its volume be at 1.2atm?

If α(alpha) moles of a monoatomic gas are mixed with β(beta) moles of a polyatomic gas and mixture behaves like diatomic gas, then [ neglect the vibrational mode of freedom

a container filled with 20 moles of ideal diatomic gas at absolute temperature T.when heat is supplied to gas temperature remains constant but 8 moles dissociated into atoms.heat energy given to gas is

a thermodynamic system undergoes a process in which the internal energy decreases by 500J .if at the same time 220J of work is done on the system,find the energy transferred to or from it by heat.

the heat absorbed by a mole of an ideal gas in a quasistatic process in which temperature changes by dt and volume V changes by dv is given by
dQ=cdt+pdv
find the change in entropy of this gas in a quasistatic process which takes it from initial values of temperature and volume to the final values of temperature and volume . does your answer depend upon the process involved in going from initial to final state ?
