Answer: The beaker will not tip over when placed on the hot plate
Justification:
Since beakers have flat surface bottoms (usually and this is the condition to use them for this particular application) they can be placed safely on the hot plate without the risk that the they tip over.
Beakers are wide mouth cylindrical vessels used in laboratories to store, mix and heat liquids. Most are made of glass, in which case the glass is resistant to the flame and does not break when exposed to high temperatures or when is heated by direct contact on a hot plate.
So, their safe shape (flat bottom) that makes them stable, along with their ability to withstand high temperatures, make them suitable to heat solutions in laboratories.

it is physical because you add another chemical to the sodium
Answer:
D- Kinetic Molecular Theory
Explanation:
. Gases consist of large numbers of tiny particles that are far apart relative to their size.
.Collision between gas particles and between particles and container walls are elastic collisions.
.Gas particles are in continuous motion. possess kinetic energy.
. Gas molecules have negligible intermolecular forces.
. Gas molecules have an average kinetic energy proportional to the ideal gas's absolute temperature.
