in this illustration we’ll analyze the external work in displacing a piston. we are given that a piston can freely move inside a horizontal cylinder which is closed from both the ends. say if we consider this is a horizontal cylinder which is closed from both the ends. and initially the piston separates the inside […]

Hello and Welcome back to my channel… I am Harikrishna M Menon from NIT Jalandhar… Today we will talk about the Zeroth Law of Thermodynamics and its implications I guess everyone will agree that the most important term in Thermodynamics is TEMPERATURE People have stated 3 laws of thermodynamics and forgot to mention Temperature or […]

Around 1159 A.D., a mathematician called Bhaskara the Learned sketched a design for a wheel containing curved reservoirs of mercury. He reasoned that as the wheels spun, the mercury would flow to the bottom of each reservoir, leaving one side of the wheel perpetually heavier than the other. The imbalance would keep the wheel turning […]

INSTRUCTOR: We’re gonna apply the first law to two closed systems, and then compare the final results. One’s a constant pressure system, piston and cylinder, pressure is .5 megapascals. The other is a fixed volume cylinder. They both contain one mole, and they’re starting at the same temperature, same pressure, so we’re starting at the […]

I’m Sean Carroll and I’m a theoretical physicist at the California Institute of Technology in Pasadena, California. And I think about how the laws of physics came to be, what they are and how they make the universe that we live in. So the Big Bang doesn’t break any of the laws of thermodynamics. The […]
