Ideal and Real Gases
Ideal gases obey conditions of the general gas laws under all states of pressure and temperature. Ideal gases are also named perfect gases. The attributes of ideal gases are as follows,
Gas Laws
Gas laws describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. The very first observations about the physical properties of gases was made by Robert Boyle in 1662. Later discoveries were made by Charles, Gay-Lussac, Avogadro, and others. Eventually, these observations were combined to produce the ideal gas law.
Gaseous State
It is well known that matter exists in different forms in our surroundings. There are five known states of matter, such as solids, gases, liquids, plasma and Bose-Einstein condensate. The last two are known newly in the recent days. Thus, the detailed forms of matter studied are solids, gases and liquids. The best example of a substance that is present in different states is water. It is solid ice, gaseous vapor or steam and liquid water depending on the temperature and pressure conditions. This is due to the difference in the intermolecular forces and distances. The occurrence of three different phases is due to the difference in the two major forces, the force which tends to tightly hold molecules i.e., forces of attraction and the disruptive forces obtained from the thermal energy of molecules.
![**Problem 14:**
A balloon can hold 10 L of gas at 2 atm of pressure. What will be the volume of the balloon at 5 atm of pressure? Assume the amount of gas and temperature are kept constant.
**Options:**
a. 10 L
b. 20 L
c. 4 L
d. 25 L
e. 5 L
When approaching this problem, use the Ideal Gas Law, specifically Boyle's Law which states:
\[ P_1 V_1 = P_2 V_2 \]
Where:
- \( P_1 \) is the initial pressure (2 atm)
- \( V_1 \) is the initial volume (10 L)
- \( P_2 \) is the final pressure (5 atm)
- \( V_2 \) is the final volume (which we need to find)
Rearrange the formula to solve for \( V_2 \):
\[ V_2 = \frac{P_1 V_1}{P_2} \]
Substituting the given values:
\[ V_2 = \frac{(2 \, \text{atm}) (10 \, \text{L})}{5 \, \text{atm}} = 4 \, \text{L} \]
So, the correct answer is:
**c. 4 L**
This demonstrates how the volume of gas will change when subjected to different pressures while keeping the temperature and gas quantity constant.](/v2/_next/image?url=https%3A%2F%2Fcontent.bartleby.com%2Fqna-images%2Fquestion%2F066bb5df-9069-4300-b122-0f92c568ce58%2F9a15beef-23db-4763-905f-7346051be9d5%2Fmnidw0g_processed.jpeg&w=3840&q=75)
