Thermochem Basics
What is the SI unit of energy, defined as N·m or kg·m²/s²?
Joule (J)
How do you convert from Celsius to Kelvin?
Add 273
What law states that the overall enthalpy change of a reaction is equal to the sum of the enthalpy changes of its intermediate steps?
Hess's Law
Which two scientists devised the concept of entropy?
Carnot, Clausius
Which French academic artist stood against modern art at the Salon des Refuses?
William-Adolphe Bouguereau
What is the transfer of energy between samples due to a temperature difference?
Heat
Adding this to a system will increase its entropy
Heat
Endothermic reactions have this type of enthalpy change.
Positive
Despite having a negative ΔG, why could a reaction not be observed at room temperature?
Takes a long time/requires its activation energy
This era of statuary is characterized by depictions of everyday citizens and statesmen with busts of figures old men rather than young warriors
Roman
What is the average kinetic energy of the particles in a sample?
Temperature
What is the equation to calculate thermal energy?
q = cp × m × ΔT
What type of reaction has a negative enthalpy change (ΔH)?
Exothermic
What term describes a reaction that will occur at room temperature because ΔG < 0?
Spontaneous
In Greek statuary, which pose relaxes one leg while flexing another?

What is the study of the transfer of energy as heat that accompanies chemical and physical changes?
Thermochemistry
What is the amount of energy required to raise the temperature of 1 g of a substance by 1 °C?
Specific Heat (Heat Capacity)
What is the enthalpy change when one mole of a compound is formed from its elements at 25 °C and 1 atm?
Molar Enthalpy of Formation
What is the measure of the randomness or disorder of particles in a system?
Entropy

Jackson Pollock
What device is used to measure energy absorbed or released as heat in a chemical or physical change?
Calorimeter
What common substance has a high specific heat?
