  LEARNING OBJECTIVES 2 At theend of 1-hour lesson, the students should be able to: 1. State the properties of gases; 2. Calculate conversion problems involving the volume and pressure; and 3. Apply the importance of conversion into real life situation
• 5.
  VOLUME One of themeasurable properties of gas, is denoted by the symbol V. It is the amount of space occupied by a gas sample.
• 6.
  INTERNATIONAL SYSTEM OFUNITS (SI) FOR VOLUME (V) 1.Liters (L) 2.milliliters (mL) 3.cubic centimenter (cm^3) 4.cubic meter (m^3) 5.cubic decimeter (dm^3)

  SAMPLE CONVERSION How manyliters (L) are in 1200 milliliters (mL) of water in a bottle? mL L 1L = 1000mL Solution: 1200 mL to L 1200 mL 1L 1 1000mL × = 1.2 L
• 8.
  SAMPLE CONVERSION How manymilliliters (mL) are 0.25 liters (L) of water in a bottle? L mL 1L = 1000mL Solution: 0.25 L to mL 0.25 L 1000mL 1 1L × = 250mL
• 9.
  PRESSURE It is thenext important measurable property of the gas, which is denoted by the symbol P. Pressure of the gas is the force exerted by the gas per unit area. In equation: Pressure (P) = force (F) / area (A)
• 10.
  INTERNATIONAL SYSTEM OF UNITS(SI) FOR PRESSURE atmosphere (atm), millimetre of mercury (mmHg). Torr bar kilopascal (kPa) pounds per square inch (psi)

  SAMPLE CONVERSION The airpressure for a certain tire is 109 kPa. What is this pressure in atmospheres? 101.325 kPa = 1 atm Solution: 109 kPa to atm 109 kPa 1 atm 101.325 kPa × = 1.075 atm or 1.08 atm kpa atm
• 12.
  SAMPLE CONVERSION The airpressure inside a submarine is 0.5 atm. What would be the height of a column of mercury balanced by this pressure? 1atm = 760 mmHg Solution: 0.5 atm to mmHg 0.5 atm 760 mmHg 1 atm × = 380 mmHg atm mmHg
• 13.
  SAMPLE CONVERSION Convert 758.7mmHg to atm. 760 mmHg = 1 atm Solution: mmHg to atm 758.7 mmhg 1 atm 760 mmhg × = 0.9983 atm mmHg atm
