The answer is 8. atomic number: the number of protons in the nucleus of an atom.
Answer: A.) Removing a few marbles from the petri dish and stirring the rest around as energy is added
B) The high temperature makes the gas molecules spread apart according to Charles's law because this law describes how a gas will behave at constant pressure.
Explanation: The phase transition from solid to liquid involves the use of energy to make the molecules present in solid to break the inter molecular forces and to start moving away from each other as in liquid. The molecules in solid are closely packed whereas in liquids they are loosely packed. Thus less number of molecules are present per unit volume in a liquid. Thus the marbles have to be removed to show less density and the energy has to supplied. Removing all but two marbles from the petri dish and shaking them vigorously as energy is added will give us a more disorderd state called gas in which the molecules are very far apart and the density is least.
B) According to Boyle's law the pressure is inversely proportional to the volume of the gas at constant temperature and constant number of moles.
(At constant temperature and number of moles)
According to Charle's law the volume is directly proportional to the temperature of the gas at constant pressure and constant number of moles.
(At constant pressure and number of moles)
Thus as temperature of the gas increases , the volume also increases, and the density decreases. the gas becomes lighter and thus rises up.
I guess if you mix them together, the chalk would get less harder.

Explanation:
Modeling crustal deformation is a very important process that helps to study plate interaction that clearly can be used to predict the likelihood of an earthquake.
Earthquake is a sudden displacement or movement with the earth that transmits elastic energy.
- Earthquakes can have shallow or deep focus depending on their location and the terrain.
- Movement on the earth are mostly noticeable along plate margins.
- This results in a world-wide movement of the broken slabs of the earth moving on the weak asthenosphere.
- It is impossible to go deep within the lithosphere to identify unstable earth.
- The uneven distribution of stress is very important in this process.
- As plate moves, the lithosphere deforms creating stresses in some area and relieving other places of stress.
- Continuous collection of stress data using strain mapping gives important parameters that can be modeled.
- Areas with high amount of stress and more movement have the highest tendency of producing earthquakes.
- A computer model is used to carry out this prediction.
- Some other factors contributes to the rapid movement but stress are by far the most important of all.
- By this, we can easily and readily hypothesize the causes of an earthquake and possible measures to mitigate it.
