Name That Term
The energy change that accompanies a reaction.
What is change in enthalpy?
Specific Heat
What is the amount of heat necessary to raise the temperature of 1g of a substance by 1oC?
This happens to the solubility of gas with increasing pressure.
What is increase?
Slowly reacting a base of unknown concentration with an acid of known concentration (or vice versa) until just enough acid has been added to react with all the base allowing the determination of the unknown concentration?
What is titration?
The enthalpy of any element in its elemental form.
What is zero?
force per unit area
What is pressure?
Standard Conditions
What is room temperature (25oC) and normal atmospheric pressure (1.00 atm)?
This happens to the freezing temperature of a liquid with added solutes.
What is decrease?
Process that absorbs heat.
What is endothermic?
What is PT = P1 + P2 + P3 + ...?
A measure of the disorder that exists in any system.
What is entropy?
Energy cannot be created or destroyed. It can only change form.
What is the First Law of Thermodynamics?
This happens to the boiling temperature of water with added solutes.
What is increase?
Process that generates heat
What is exothermic?
Hess's Law
Activation energy
What is the energy necessary to start a chemical reaction?
The specific heat of water
What is 1.000 cal/goC or
4.184 J/goC
This happens to the pressure in a constant T closed gas system with increased volume.
What is P will decrease (Boyle's Law)?
The type of reaction that produces a Negative delta H
What is exothermic?
Combined Gas Law
P1V1/T1 = P2V2/T2
or
PV/T = constant
Any quantity that depends solely on the final destination, not in the way we get to that destination.
