System - The portion of the universe we have singled out for study surroundings - Everything else in the universe universe - System and surroundings work - the action of a force through a distance heat - Transfer of energy from hotter to colder object heat capacity - The amount of heat needed to raise the temperature by 1 K Heat Tax - Increase in surroundings comes from the heat from the system Kinetic energy - Energy of motion potential energy - Energy of an object by virtue of its posi...

What are open and closed systems? - ANSWER-Closed systems (control mass) are those in which a fixed amount of mass is contained (no mass can cross the system boundary). The system boundary can be fixed or movable. Energy may cross the boundary. In an open system (control volume), mass and energy can enter and exit the system. What are extensive, intensive, and specific properties? - ANSWER-Intensive properties are independent of the mass of a system (eg. T, p, density). Extensive proper...

This pdf has indepth explanation of Heat and thermodynamics written in simple manner

The branch which deals with the movement of energy from one form to the other and the relation between heat and temperature with energy and work done is called as thermodynamics. In other terms we can define thermodynamics as the science stream that deals with the study of the combined effects of heat and work on the changes of state of matter confined by the laws of thermodynamics.

It is the best short notes for students to tackle the questions of chemistry easily!

This document contains definitions that cover the subject of Thermodynamics to assist you in understanding many diverse concepts related to the subject for your studying success. This document contains definitions that focus on Thermodynamics designed to help you gain knowledge in learning precise meanings and foster an understanding of the definitions. Learning these definitions will help you provide clarity.

Adiabatic walls: no energy may be transferred as heat between the system and the surroundings → no heat added or removed and no change in entropy ○ ∆U=-W; ∆S=0 ● Diathermal walls: the temperature of the system and the surroundings are the same (thermal equilibrium: the surroundings are sufficiently large so that their heat capacity is infinite and they can transfer heat to or from the surroundings with no change in temperature) ○ Isothermal means that the system is in thermal equili...
