Transcribed Image Text: 1-10. 4.35 L of a gas is at 1.16 atm. What pressure is obtained when the volume is
9.3 L?
11-20. A gas is collected and found to fill 4.73 L at 35.0°C. What will be its volume at
standard temperature?
NOTE: convert 35.0°C to Kelvin and you get 308 °K.
Definition Definition Any of various laws that describe the ways in which volume, temperature, pressure, and other conditions correlate when matter is in a gaseous state. At a constant temperature, the pressure of a particular amount of gas is inversely proportional with its volume (Boyle's Law) In a closed system with constant pressure, the volume of an ideal gas is in direct relation with its temperature (Charles's Law) At a constant volume, the pressure of a gas is in direct relation to its temperature (Gay-Lussac's Law) If the volume of all gases are equal and under the a similar temperature and pressure, then they contain an equal number of molecules (Avogadro's Law) The state of a particular amount of gas can be determined by its pressure, volume and temperature (Ideal Gas law)
