Okay in an example problem for Charles Law, my teacher had the information; T1 = 317 K V1 = 250 cm^3 T2 = 273 K V2 = ?? When she put all the information in the equation she go the answer V2 = 215.2996845 cm^3 But then she changed it to 220 cm^3 Could someone just explain to me how and why she did this?

    that don't make any sense she should have simplified to 215 cm^3 not 220. There is no good reason to round the answer that high

    maybe it was because the first volume only had two significant numbers so your teacher changed the second volume to have two as well

    Well thank you. I didn't think it made any sense either.
