Answer:
When Logan opens a new bottle of carbonated beverage, the sudden release of pressure causes the beverage to bubble up and overflow. What could Logan do in the future to prevent the next bottle from overflowing when he opens it.
Explanation:
This is an application of Boyle's law.
According to Boyle's law:
the volume of a fixed amount of gas is inversely proportional to its pressure at a constant temperature.
![V \alpha \frac{1}{P}](https://tex.z-dn.net/?f=V%20%20%5Calpha%20%20%20%5Cfrac%7B1%7D%7BP%7D)
So, if pressure reduces all of a sudden, the volume increases and this causes an overflow of the beverage from the bottle.
To avoid this situation, the pressure inside the bottle should not be released at once. The bottle cap should be opened slowly in such a way that opens a little and then close again open a little and then close like that many times if we do, then pressure inside the bottle goes slowly then, the volume will not increase all of a sudden.
The statement is true. The relationship between the kinetic energy of molecules and the temperature of these molecules are in direct proportionality. Therefore, the temperature generally increases as average kinetic energy also increases. We can relate the two qualities using the Boltzmann equation.
Answer:
by using ideal gas law
Explanation:
ideal gas law:
PV=nRT
where:
P is pressure measured in Pascal (pa)
V is volume measured in letters (L)
n is number of moles
R is ideal gas constant
T is temperature measured in Kelvin (K)
by applying the given:
P(initial) V(initial)=nRT(initial)
P(final) V(final)=nRT(final)
nR is constant in both equations since same gas
then,
P(initial) V(initial) / T(initial) = P(final) V(final) / T(final)
then by crossing multiply both equations
V (final)= { (P(initial) V(initial) / T(initial)) T(final) } /P (final)
P(initial)=P(final)= 1 atm = 101325 pa
V(initial)= 6 L
T(initial) = 28°c = 28+273 kelvin
T(final) = 39°c = 39+273 kelvin
by substitution
V(final) = 6.21926 L
The scientist will repeat the experiment to make sure that
his results are reliable.
