the study of the transfers of energy as heat that accompany chemical reactions and physical changes.
What is Thermochemistry?
100
the amount of energy required to raise the temperature of one gram of a substance by one Celsius degree (1°C) or one kelvin (1 K)(because the sizes of the degree divisions on both scales are equal)
What is Specific Heat?
100
The enthalpy change that occurs during the complete combustion of one mole of a substance
What is Enthalpy of Combustion?
200
The energy absorbed or released as heat in a chemical or physical change is measured in a calorimeter
What is Calorimeter?
200
the amount of energy absorbed by a system as heat during a process at constant pressure
What is Enthalpy Change
200
The overall enthalpy change in a reaction is equal to the sum of enthalpy changes for the individual steps in the process
What is Hess's Law?
300
measure of the average kinetic energy of the particles in a sample of matter
What is Temperature?
300
the quantity of energy transferred as heat during a chemical reaction.
What is Enthalpy of Reaction
300
measure of the degree of randomness of the particles, such as molecules, in a system
What is Entropy?
400
the SI unit of heat as well as all other forms of energy
What is Joule
400
an equation that includes the quantity of energy released or absorbed as heat during the reaction as written
What is Thermochemical Equation
400
combined enthalpy-entropy function
What is Free Energy?
500
can be thought of as the energy transferred between samples of matter because of a difference in their temperatures
What is Heat?
500
the enthalpy change that occurs when one mole of a compound is formed from its elements in their standard state at 25oC and 1 atm.
What is Molar Enthalpy of Formation
500
difference between the change in enthalpy, ΔH, and the product of the Kelvin temperature and the entropy change, which is defined as TΔS.
