Gas Law Questions and Answers (Q&A)

Is this not Charles Law? Is pressure not constant?
​V1T2=V2T1
.43mLXT2=1mLX299K
​T2=1mLX299k/ .43
T2= 695.3488372K
​I'm confused as to why this isn't the answer.

Based on the given, the flask with the most molecules is task 4. The answer will be based on Boyle’s Law. It states that a fixed amount of ideal gas is placed at a certain temperature, the pressure and the volume will be inversely proportional.

This means that they will always have an inverse relationship with each other. If you would check the number of molecules that are available for each flask, you can see that they all have different amounts. Out of the 4, the 4th flash has the highest amount of pressure which also means that it has the most molecules present. The high level of molecules is causing pressure against the flask.

This is caused by the molar mass of the molecules and the volume of the container

There are two standard laws regarding gas. The Charles law and the Boyles law. They state that, if the pressure is constant, the volume of gas is inversely proportional to the temperature. This means that when the volume will increase, the temperature will decrease. Likewise, at a constant temperature, the pressure is inversely related to the volume. As the volume decreases the pressure of the gas increases.

This helps us figure out the correct relations between the quantities, helping physics figure out the particular behaviors of different gases at a different temperature. It also helps them figure out the changes in the pattern of the gas at different pressures and volumes, unraveling its mysteries.

Helium is an element on the periodic table. It is a pervasive element that can be found in many different places. It has an atomic number of two. It is the second most common element found on earth. Only hydrogen is in more supply. You can’t see this gas because helium has no color, odor or taste to it.

Helium is known for causing balloons to go up into the air. It is located in the category of noble gases. This is group eighteen. Helium can be turned into a gas if it is at the right temperature. To do that, this gas must be at negative four hundred fifty-seven degrees Fahrenheit to be turned into a liquid.

The correct answer is option C
By decreasing the container volume you can increase the pressure of a gas assuming the temperature remains constant. Keep in mind that pressure is inversely proportional to volume at a contain temperature.

This simply means, the more the volume the lesser the pressure, and the lesser the volume, the more the pressure.

Option A is wrong because increasing the container volume will decrease the pressure and not increase it.
Option B is wrong because increasing the volume of gas will further decrease the pressure.

If in case you need help in answering this question, you should refer to Boyle’s Law. The pressure of a given mass of an ideal gas is said to be inversely proportional to its volume. This means that as the pressure becomes higher, the volume becomes lower and vice versa.

Based on the given, flask 1 is the smallest which also means that it has the highest amount of pressure. Take note that Boyle’s law can be applied as long as the temperature remains constant. This formula can be used P=1/V if in case there are some computations that you need to do to solve the question.

The answer is 1. The first flask would possess the lowest pressure if each of these flasks contains the same number of gas molecules. As the temperature increases, the pressure of the flask also increases. Therefore as the pressure decreases the temperature also decreases so the flask with the lowest temperature would also have the lowest amount of pressure.

The increase in temperature means that the molecules speed up and hit the flask more often. This causes the pressure in the flask to become higher. The same can be said for molecules with a decrease in temperature. The molecules bump into each other and the sides of the flask less often.

Boyle's law states that pressure (P) and volume (V) are inversely proportional.Charles' law states that volume (V) and temperature (T) are directly proportional.Gay-Lussac's law states that pressure (P) and temperature (T) are directly proportional.
