Gas Laws Flashcards
what is the formula for Boyles Law?
p1v1=p2v2
what is atmospheric pressure and it’s approximate value?
pressure exhorted by the atmosphere. 1 bar or 101.3kpa
what is the formula for Charles Law?
v1/t1=v2/t2
what is the formula for ideal gas law?
p1/t1=p2/t2
how is gauge pressure calculated?
absolute pressure - atmospheric pressure
what is STP?
Standard Temperature and Pressure
what is STP temperature and pressure?
0 degrees or 273 Kelvin and 101.3 kpa or 14.5 psi
how to convert Celsius to Kelvin?
add 273
what is the formula for absolute pressure?
gauge pressure + atmospheric pressure
define Boyles law
changes that occur in constant temperature (isothermal)
define Charles law
changes in constant pressure (isobaric)
what is temperature and how is measured?
a measure of how hot or cold a substance is and is measured in degrees Celsius or degrees Fahrenheit
what is the formula for combined gas law?
p1v1/t1= p2v2/t2
what is the unit for the thermodynamic temperature scale?
Kelvin
Atmospheric pressure may also be known as ?
barometric pressure
what is pressure?
the force exherted equally per unit area of a surface
what is the unit for pressure
PA ( Pascals)
what is the formula for pressure?
PA= Force/ Area
