let's say some amount of heat is absorbed by a refrigerant for phase change at a low pressure. will this heat absorbed be equal to the heat given out by the compressed refrigerant at high pressure? i know that the amount of heat required for phase change from liquid to vapour is less at low...

what role dos the reversibility play in making the carnot cycle most efficient?

thanks! :)

cusps? :P

at 3:30 he introduces heat content to show why it can't be a state variable. he says that if q=2 is added to the cycle everytime you go around the cycle the heat content would be incremented by 2. but as heat=work shouldn't that extra 2 be lost as work and at point 1 you always have hc=5? watch...

in a spring mass damper system subjected to a periodic force. the response of the system only depends on the force and the restoring forces caused due to the spring is ignored because the damper is assumed to have taken care of it. now it's here that my confusion originates. in a damped free...

thanks! :) i think i get it..

finding out non trivial solution of two linear algebraic equations means we have to equate the determinant of the coefficients to zero which in turn means the slope of the two lines are same and they lie on each other. so what is the use of two equations for this? can we get the points or...

when a rotating wheel precesses about an axis as in a motorcycle taking a turn it experiences a force in the upward direcion. I've read in my book that this gyroscopic effect takes place due to the principle of conservation of angular momentum.it says the angular momentum changes due to the...
