What happens to the pressure of a gas if it is cooled down while the volume of the container it is in remains constant? Select one: O a. pressure decreases O b. pressure remains the same O c. pressure increases O d. it cannot be predicted A 5.6 liters sample of gas in a piston has a pressure of 1.5 atm. The piston is compressed until its volume is 4.8 L. What is the new pressure of the gas inside the piston (in atm)? DO NOT INCLUDE UNITS IN YOUR FINAL ANSWER. Answer: A small research submarine with a volume of 1.2 x 105 L has an internal pressure of 1.0 atm and an internal temperature of 15 °C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 3° C, what will the volume of the gas (in L) inside be if the hull of the submarine breaks? .

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.

**Question 3:**
A small research submarine with a volume of \(1.2 \times 10^5\) L has an internal pressure of 1.0 atm and an internal temperature of 15 °C. If the submarine descends to a depth where the pressure is 150 atm and the temperature is 3 °C, what will the volume of the gas (in L) inside be if the hull of the submarine breaks?
