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 •

Outline on nuclear energy

Definition: energy from nuclear fission or fusion: the energy released by nuclear fission or fusion

What is the mass defect

If you add the exact mass of the protons, neutrons, and electrons in an atom you do not get the exact atomic mass of the isotope. The diference is called the mass defect. The difference between the mass of the atomic nucleus and the sum of the masses of the particles within the nucleus is known as the mass defect.

What is entropy and which phase of matter has the the highest entropy

Plasma

How to Put these photons in order of increasing energy

A photon with energy 3.0 x 10-19 J

A photon with wavelength 525 nm

A photon with frequency 7.6 x 1014 Hz

A photon with frequency 2 x 1015 Hz

Is nuclear chain reaction is called fusion

No

The nuclear chain reaction is called nuclear fission not fusion,

How much energy does it take to melt a 16.87 g ice cube

636 J

Which quantum number deals with shape

The second quantum number, or "l" which describes the subshell (s, p, d, f, etc).

Why can light be treated like a particle

Light comes in chunks of energy called photons.

What information is obtained from radioactive dating

The age of an object that was once living.

What does binding energy measure

The energy used to hold the nucleus together

What best describes a radioisotope

its nucleus is unstable
