(PLEASE HELP NEED ANSWER ASAP!!)
(PLEASE HELP NEED ANSWER ASAP!!)
2 answers:
Answer:
B) Boiling it at its boiling point
Explanation:
As we know that the heat required to convert the given substance from liquid to vapor at its boiling point is known as latent heat of vaporization
So here we know that
here we know that
so it is known as the heat required to boil the given substance of unit mass at its boiling point
so correct answer will be
B) Boiling it at its boiling point

Answer:
Pressure of the gas = 12669 (Pa) and height of the oil is 1,24 meters
Explanation:
First, we can use the following sketch for an easy understanding, in the attached image we can see the two pressure gauges the one with mercury to the right and the other one with oil to left. We have all the information needed in the mercury pressure gauge, so we can determine the pressure inside the vessel because the fluid is a gas it will have the same pressure distributed inside the vessel (P1).
Since P1 = Pgas, we can use the same formula, but this time we need to determine the height of the column of oil in the pressure gauge.
The result is that the height of the oil column is higher than the height of the one that uses mercury, this is due to the higher density of mercury compared to oil.
Note: the information given in the units of the fluids is not correct because the density is always expressed in units of (mass /volume)
