Answer to Question #142157 in Physical Chemistry for Hadden

Question

Define the basic terms-isolated system, state function, energy, heat, enthalpy

Answer 1

An isolated system refers to a thermodynamic system that cannot exchange either energy or matter outside its boundaries.

State function is a quantity in thermodynamics, such as entropy or enthalpy, that has a unique value for each given state of a system.

Energy is the ability to do work.

Heat is a form of energy that is transferred between systems or objects with different temperatures.

Enthalpy is the product of pressure and volume as well as the sum of internal energy of a thermodynamic system.

H = E + PV
