This Physics video derives the equation for the electrostatic potential energy of a charge in an electric field. This playlist covers Electrostatics topics such as charge, Coulomb's Law, Electric Field, Electric Potential (due to point charges and uniform fields, Gauss's Law, and fields and potentials of different charge distributions. https://youtube.com/playlist?list=PLm_WLG6GdV3tmDw8JCqnwQwB4OJuvU3A8 Post your comments/questions below and please subscribe. #DrOfEng #physics #electricity_and_magnetism

Physics video, worked example, thermodynamics problem. A PV diagram of a heat engine is shown below. - Describe the difference between isothermal and adiabatic compression. - Determine if heat is absorbed or dissipated by the system along the isotherm AB. - Describe why heat cannot be fully converted into work using an example of a heat engine. - Does the system do work on the surroundings, or vice versa, when it goes through the cycle ABCDA? - If the system goes through the cycle in reverse i.e. ADCBA, is there a net gain or net loss of heat and why?

Physics video, worked example, thermodynamics problem. An ideal gas is transformed from state A to state C according to the PV diagram below. Assume that 80J of heat flows into the system and the work done by the system is 35J when transformed along path AB a) Determine the work done by the system along path BC b) If the system’s state returns from C to A along the isotherm AC, find the change in internal energy c) If the surroundings do 15J of work on the system along the isotherm, determine the amount of heat added or removed from the system. d) What is the work done over the entire cycle ABC? Is the net work done on or by the system? e) What is the heat flowing in or out of the system along BC? Post your comments/questions below and please subscribe. #physics #thermodynamics #DrOfEng

Physics video, worked example, thermodynamics problem. Joule’s experiment is shown below, where a Helium gas is placed in container A which is shut off from container B with a stopcock. Container B is evacuated and both containers are placed inside a calorimeter. a) When the stopcock is opened, the gas flows to container B and the thermometer shows a negligible change in temperature. Explain why using the first law of thermodynamics b) If Neon gas is placed with the Helium gas inside container AB (stopcock removed), what is the ratio of the kinetic energy of both gases in the mixture, assuming they are in thermal equilibrium (the molar mass of Neon is higher than Helium)? c) Sketch the Maxwell-Boltzmann distribution for both gases (number of gas particles Vs the velocity) and identify the root mean square velocity for both gases Post your comments/questions below and please subscribe. #physics #thermodynamics #DrOfEng
