Sci physics

• Volume is measured by liters(L) in chemistry
• Liters is also called cubic decimeter
• If volume is constant the walls cannot move
• when generalized variable is discussed, the symbol T is used.
• Celsius is from Andres Celsius
• The sign of celsius should always be in a capitalized letter
• If we are converting celsius to kelvin we should use the formula C + 273.15
• gas pressure is created by the molecules hitting the wall of a container. 
• 3 different units of pressure used in chemistry are atmosphere, millimeters of mercury and kilopascals
• kilopascal (kPa) = 1000 pascals
• atmosphere (atm) = 101325 pascals
• the amount of gas present is measured as moles(mol) 
• Boyles law equation is P1V1 = P2V2
• Standard pressure is defined as 1 atm or 760 mmHg/torr or 101.325 kPa and 101,325 Pa 
• another very important gas behavior is kelvin scale(K)
• kelvin is from lord kelvin, given name was William Thompson
• when the generalized variable of amount in moles is discussed (n) is used as symbol
• Higher V, Lower P and Higher P, Lower V
• kelvin scale has no degree sign
• boyles law - tempareature is constant
• boyles law - P1V1 = P2V2
• boyles law is from Robert Boyles
• if p goes down by half then v will increase 2 times
• charles law - T1V2 = T2V1
• boyles law - inversely proportional
• charles law - pressure is constant
• charles law - directly proportional
• charles law - Increase T, Increase V and Decrease T, Decrease V 
• boyles law - Higher V, Lower P and Higher P, Lower V
• Charles law is from Jacques Charles
• gay lussacs law - directly proportional
• gay lussacs law - volume is constant
• gay lussacs law - P1T2 = P2T1
• avogadros law - amadeo avogadro
• avogadros law - volume is constant
• avogadros law - V1n2 = V2n1
• avogadros law - directly proportional
• combined gas law - P1V1T2 = P2V2T1
• R - gas constant = 0.0821(L * atm / mol * K)
• Ideal gas law - PV = nRT
