CHEM1101 - Resources for Week 9
Topics and Learning Outcomes
Thermochemistry
define system, surroundings and universe for simple thermodynamic processes
explain the difference between heat and temperature
use the First Law of Thermodynamics to calculate the change in internal energy accompanying heating and expanding an ideal gas
relate temperature and heat change using specific and molar heat capacities
calculate internal energy changes using the bomb calorimeter
Enthalpy
define the difference between internal energy and enthalpy
