Energy used to cause an object that has mass to move
What is work?
100
SI unit of energy
What is the Joule?
100
The First Law of Thermodynamics states this
What is energy is neither created nor destroyed?
100
The internal energy plus the product of pressure and volume
What is Enthalpy?
100
This apparatus can be used to measure the change in Internal Energy, which is very close in value to the change in Enthalpy
What is a bomb calorimeter?
200
Energy used to cause the temperature of an object to rise
What is heat?
200
Another way energy is released from a system (other than work)
What is heat?
200
By definition, the change in internal energy, deltaE, is
What is the final energy of the system minus the initial energy of the system.
200
When the system changes at constant pressure, the change in enthalpy can be described by this formula
What is deltaH=deltaE + P*deltaV
200
Hess' Law states
What is “if a reaction is carried out in a series of steps, deltaH for the overall reaction will be equal to the sum of the enthalpy changes for the individual steps.”
300
Energy an object possesses by virtue of its motion
What is Kinetic Energy?
300
The formula used to express work
What is w=F x d
300
The energy change when the system has absorbed energy from the surroundings
What is endergonic?
300
The change in Enthalpy is also described as the heat of reaction. The reason for this can be described mathematically
What is deltaH=q
300
The change in Enthalpy depends on this
What is the initial state of the reactants and the final state of the products?
400
Energy an object possesses by virtue of its position or chemical composition
What is Potential Energy?
400
An expression used to define Kinetic Energy
What is Ek=1/2mv2
400
This process is described by heat being released by the system into the surroundings
What is exothermic?
400
Enthalpy is this type of property
What is an extensive property?
400
the enthalpy change for the reaction in which a compound is made from its constituent elements in their elemental forms
What is the Enthalpy of Formation?
500
The most important form of potential energy in molecules
What is Electrostatic Potential Energy?
500
This type of energy is often equal to zero when a ball is sitting at the top of a hill
What is Kinetic Energy?
500
The signs for q, w, and delta E when the system loses heat, does work is done on the system, and there is a net loss of energy by the system
What is -q, +w, and -deltaE
500
The amount of energy required to raise the temperature of 1 g of a substance by 1 K (or 1 degreeC). This can be calculated using a specific formula
What is the specific heat capacity or specific heat?
What is s=q/(m*deltaT)
500
This is very important to remember when using Hess' Law
What is taking the coefficients of the balanced reaction into account?
