Una determinada cantidad de gas que ocupa un recipiente de 2,5 L y ejerce una presión sobre las paredes del mismo de 3,2 atm ¿qué presión ejercerá si el volumen lo reducimos a 1,2 L manteniendo
constante la temperatura?
¿y si lo aumentamos a 4,6 L?

Aphysical change is one that you can put in and remove like a ham sandwich. the stuff you put in there can be changem its not permanet. a chemical change is on that can't be change thats permanet. like when you make a cake and bake it. you can't get those ingredients back.

Cause its being chemically applied?
