Chapter 10 notes Gases and Their Properties Note*** when you do calculations for gases the temp must be in absolute scale (Kelvin) so you’ll have to convert if the problem is stated in ℃. (+273) = K ex) 26℃ → K 26℃ + 273 = 299 K I. Pressure A. Pressure is the force exerted on an object, divided by the area over which the force is exerted. P = force = F area A B. SI units of pressure ● The SI unit is the Pascal, but in chemistry we use the units of atmosphere (atm) or either or the following: (Some helpful pressure u
