Carnot Cycle - An Ideal Heat Engine 

Thank you so much 😀

Physics wallah??

@@likithraj5139 No

It all matrix in which we are

Can u help me I didn't understand

@@ameenhussain4167 it is a sudden change.. where the internal energy that the gas has accumulated is used up or released in expansion or compression

no its not isothermal overall, the condition for that would be dT=0, temperature must NOT change at any given moment do not just prioritize final and initial temperature difference. As for your last statement that's not true, isothermal and adiabatic are usually exclusive of each other like he said during the adiabatic expansion/compression the temperature changed(not isothermal) without involvement of heat(adiabatic)

actually, in Carnot cycle air first expends that's why it gets cool down. because no external supply of heat is there. here expansion of air is a cause and cooling down is after effect of this cause. what you are saying is that cooling down is a cause and after effect will be compression. this is a different thing.

@@Fizica. smaj nhi aya...kindly explain in simple words...plz..it is my question too...kindly clear this doubt in simple words

the gas in the adiabatic expansion is actually losing out internal energy and this is doing work on piston to lift it up.this process is done until gas reaches at equilibrium pressure with the surrounding. the entropy remains unchanged..... the person who made this video is dumb in explanation...but good animation.
