. A heat engine is used to drive a heat pump. The heat transfers from the heat engine and from the heat pump are used to heat the water circulating through the radiators of a building. The efficiency...

we knowthat principle of calorimetry :heat lossed by the hotbody is equal to heat gained by the cold body there we know that Q=mc(dt) therefore equating to theheat gained by cold body given total mass...

dear satu derivation is not required for this , u can understand by simple logic at constant volume , the work done is 0 , therefore , whole of heat supplied is used in increasing the temperature , at...
Excuse me....I have the same question in my physics module/sheet of class 11 resonance institute Kota. But they have given answer-[1+(¥2)(delta T)]÷[(1+(¥1)(delta T)]
Doubt is that how to find the exact volume flow rate of air in a specimen( filter or regulater ) we manufacture. we use Q=(diff pres x tank vol)/ time in sec. is it right, if not pls brief.
Hi Sofi, this is your required relation …............................................ if want its derivation you can ask :)
1*546+1*(100-)t=1*80+t 546+100-100t=80t here t is -ve this means the amount of heat released when 1 g of steam condenses is very more enough to convert all the ice into water at 0 degreee c
