For a diatomic gas change in internal energy for unit change in temperature for constant pressure and constant volume is U1 and U2 .then what is their ratio? A-5:3,B-3:5,c-1:1,D-5:7

Asked by Priyanka 7th November 2017 2:32 PM

The relation between internal energy, pressure and volume of a gas in an adiabatic process is U=a+bPV.where a and b are positive constant. Then what will be value of gamma?i.e cp/cv ratio. A-a/b,B-b+1/b,D-a+1/a,c-b/a

Asked by Priyanka 7th November 2017 2:41 PM

Sir, could you please explain me why did you take U=nCvdt here? As internal energy only depend on temp..

a thermally insulated rigid container contains an ideal gas.if it is heated through a resistance of 100ohm by passing current of 1ampere for 5 minutes then change in intenal energy of gas?a-0kj,b-30kj,c-10kj,d-10kj

a system absorbs 500J of heat and does work of 50J on its surroundings. calculate the change in internal energy

Asked by gganga 13th April 2018 6:34 PM

A system has internal energy equal to U1 600J of work is done on the system when 450 J of heat is lost. The final energy of system is_________________________. for this.. the formula is  U=Q+W   OR   Q=U+W

Asked by imtiyazmulla68 2nd May 2018 7:49 PM

A system absorb 20 kJ heat and also does 10 kJ of work. The net internal energy of the system is :- (1) increases by 10 kJ (2) decreases by 10 kJ (3) increases by 30 kJ (4) decreases by 30 kJ

A container is filled with 20 moles of an ideal gas at absolute temperature T. When heat is supplied to gas temperature remains constant but 8 moles dissociate into atoms. Heat energy given to gas is-(1)4RT, (2)6RT, (3)3RT, (4)5RT

100 g of water is heated from 30°C to 50°C.Ignoring the slight expansion of the water ,the change in its internal energy is (Take,specific heat of water is 4184 J/Kg/K).     Personally I want to know what is slight expansion and anotherly is the work done here is zero ,if yes how??

A swimmer coming out from a pool with a film of water weighing about 18 g .how much heat must be supplied to evapourite this water?also calculaye internal energy of vapiurisation at 100℃ given Enthalpy of vapiurisation at 373k is 40.66kj/mole

Find internal energy

Asked by ashutosharnold1998 3rd November 2019 8:22 PM

The increase in the energy appears as heat of the body

Asked by Contactsangeetak 1st December 2019 7:22 PM

1 kg of water at 373 K is converted into steam at same temperature. Volume of 1 cm3 of water become 1671 cm3 on boiling. What is the change in the internal energy of the system if the latent heat of vaporisation of water is 5.4×10^5 cal/kg? Temp and pressure to constant .How to know whether isobaric or isothermal?
