A sample of argon gas at a pressure of 715 mm Hg and a temperature of 26oC occupies a volume of 8.97 L. If the gas is heated at constant pressure to a temperature of 71oC, what will be the volume of the gas sample in cubic centimeter, cm3? A sample of hydrogen gas at a pressure of 0.52 atm and a temperature of 424.83 K occupies a volume of 857 mL. If the gas is heated at constant pressure until its volume is 1.02 x 103 mL, what will be the Celsius temperature of the gas sample? Kindly write the given, solution, and answer clearly so that I can understand it well. Thank you.
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.

A sample of gas has an initial volume of 285 mL at a pressure of 857 torr and a temperature of 25.0 C. If the gas is compressed to a volume of 85.2 mL and heated to a temperature of 100.0 C, what is it's final pressure in atm?
