Read moreQuestion 1 Below diagram shows a process ABCA performed on an ideal gas. Find the net heat given to the system during the process. SolutionAs process ABCA is a cyclic process so net…
Read moreQuestion 1 A sample of an ideal gas is taken through the cyclic process abca (as shown in diagram below). It absorbs 50 J of heat during the part ab, no heat during…
Read moreA Heat Engine is a device by which a system is made to undergo a cyclic process that results in conversion of heat to work. Usually Heat Engines consists of Hot reservoir (kept…
Read moreSuppose that we’ve put in some gas into a container with a piston on top of container. If we put this container on top of a heater (like a simple burner) then slowly…
Read moreWhen a particle is constrained to move on a straight line, we say that object is in Straight Line motion. Generally we choose the straight line as X-axis and a suitable time instant…
Read moreIf the velocity of a particle remains constant as time passes, we say that it is moving with uniform velocity. If the velocity changes with time, it is said to be accelerated. The…
Read moreThe average velocity of a particle in a time interval t1 to t2 is defined as its displacement divided by the time interval. For example – If the particle is at a point…
