Everything is thermodynamics. Hi, I'm Cherry and welcome to my blog. The topics are all about the three laws of thermodynamics. Please leave a comment/feedback to improve the contents of my work, it will be fully appreciated! Thanks!
1.) Which of the following represents the first law of thermodynamics? Explain. - After falling down the hill, a ball's kinetic energy plus heat energy equals the initial potential energy - If a refrigerator is unplugged, eventually everything inside of it will return to room temperature - Two systems in equilibrium with a third system are in equilibrium with each other - The specific heat of an object explains how easily it changes temperatures - While melting, an ice cube remains at the same temperature ANS: After falling down the hill, a ball's kinetic energy plus heat energy equals the initial potential energy 2.) A gas in a closed container is heated, causing the lid of the container to rise. The gas performs 3J of work to raise the lid, such that is has a final total energy of 15J. How much heat energy was added to the system? ANS. 18J 3.) A gas in a closed conta...
