What is thermal energy

The total kinetic energy of the particles in a system

What is thermodynamics

the study of the movement of energy and heat.

or

Thermodynamics is the branch of physics concerned with the conversion of different energy forms.

•DeltaG (rxn) = DeltaG (pdts) - DeltaDG (rcts) •DeltaG°(rxn) = -R T ln K •

What are quarks

Quarks are any of a group of subatomic particles thought to be among the fundamental constituents of matter more specifically, of protons and neutrons.

The concept of the quark was first proposed by Murray Gell-Mann and George Zweig ; its name was taken from James Joyce's novel Finnegans Wake. Quarks include all particles that interact by means of the strong force. They have mass and spin, and they obey the Pauli exclusion principle. They have never been resolved into smaller components, and they never occur alone. Their behaviour is explained by the theory of quantum chromodynamics, which provides a means of calculating their basic properties. There are six types of quarks, called up, down, strange, charm, bottom, and top. Only the up and down quarks are needed to make protons and neutrons; the others occur in heavier, unstable particles. Subatomic particles that make up protons and neutrons

Who created the model of the atom that has quantizied levels of energy
What does a negative H tell about a reaction

The reaction is exothermic.

Which of the following would be a good situation in which to apply Hess's law

Scale step reactions so products/reactants that don't appear in the target reaction will cancel out.

What would cause entropy to decrease in a reaction

The products becoming more ordered than the reactants

Which equation shows how frequency is related to velocity and wavelength

F=v/&

What information does Gibbs free energy give about a reaction

It tells if the reaction will process spontaneously or not

What is the value for G at 300 K if H 27 kJmol and S 0.09 kJmolK

G = 0 kJ/mol

What does S0 mean

the system has become more random

What statement best describes the potential energy diagram of an endothermic reaction

The potential energy of the products is greater than the potential energy of the reactants.

What is the wavelength of a light of frequency 4.47 X 1014 Hz

The wavelength is 671 nm.
