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 is a prism

something that splits up light into different colors ! apx :)

What makes a nucleus unstable

The strong nuclear force doesn't balance the electrostatic force.

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 the energy J of photon with a wavelength of 601nm

what is the energy of J of photon with a wavelength of 601nm?

What does the wavelength of an EM wave tell about its energy

As the wavelength decreases, the energy increases.

Who created the model of the atom that has quantizied levels of energy
Which of the following is an example of quantization

The fans sitting in the bleachers

Why can light be treated like a particle

Light comes in chunks of energy called photons.

What information does the third quantum number of electron give

the specific orbital the electron is in.

What causes lines in a line spectrum

Wavelengths of absorbed or emitted photons

Every line in a line spectrum is caused by a transition, from one quantum state to another quantum state, involving electrons.

What does the second quantum number (I) describe

Which sub level the electron is in.

How much energy is released is a sample loses 0.05 kg mass through radioactive decay

4.5 × 1015 J

What is the first quantum number of a 1s2 electron in phosphorus

The first quantum number (n) represents the energy level (shell), so for a 1s2 electron, it would have a value of 1.

What is nuclear fission

the splitting of a nucleus
