Answer:
You were a freeloader of my questions, so I'll be one too.
The difference between conductors and insulators is because
of electronic structure of atoms and molecules.
Anywhere we have free electrons, we have a hard conductor
where free electrons help in conduction.
In electrolytes, charged Ions do conduction.
Dielectrics (or insulators) don't have free electrons current.
Free electrons mean, the electrons that are not related with
a specific atom, they are allowed to move nearby the crystal lattice.
Answer:
B) uniform
Explanation:
We can solve this problem by using Boyle's law, which states that:
<em>For a constant mass of an ideal gas kept at constant temperature, the pressure of the gas is inversely proportional to its volume.</em>
Mathematically:
where
p is the pressure of the gas
V is its volume
If we apply the equation to the bottle in the problem, we see that:
- when the volume of the bottle (and therefore, of the gas inside) decreases, than the pressure will increase
- viceversa, when the volume of the bottle increases, the pressure will decrease
The amount by which the pressure increases is inversely proportional to the decrease in volume, so the answer depends on how the volume of the bottle decreases: however, if the volume of the bottle decreases uniformly, then we can say that the pressure inside the bottle will also increases uniformly.
