"Ideal gas as an approximation that helps us model and predict the behavior of real gases. The term ideal gas refers to a hypothetical gas composed of molecules" using the equation PV=nRT REAL WORLD EXAMPLE: a balloon being filled with hot gas in constant pressure and temperature allowing the volume to increase, adding more gas particles will fill the balloon
"At constant volume...temperature and pressure are directly proportional" REAL LIFE SITUATION: Tires in the winter lose their pressure which explains why the low pressure alert comes on most of the time in the winter because pressure as explained by this gas law is effected by temperature
"At constant temperature...pressure and volume are inversely proportional" (NOTES) REAL WORLD SITUATION: when a soda can is opened the pressure inside the can allows bubbles to form and "fizz"
" At constant pressure temperature and volume are directly proportional" where temperature is always measured in Kelvin (NOTES) REAL WORLD SITUATION: the pressure in your car's tire changes when the seasons change such as when its winter the pressure is lower than in the summer when it higher.
