charles' law and whipped cream?

[Sarah M]

can someone please explain to me how charles' law and whipped cream are related?? Charles Law is the relationship between volume and temperature at a constant pressure. So as temperature increases, volume increases too. And as temperature decreases, volume decreases too. It can be related to whipped cream in a can or just home made whipped cream

Charles' law relates volume and temperature. The pressure is constant. The usual experiments involve balloons or cylinders with pistons. Whipped cream is filled with countless cells filled with air, which behave in the same way. If the whipped cream is free to expand or contract the cells, then it will obey Charles' law. This does not apply to whipped cream in a can, because the stuff is confined. So heating canned product causes the pressure to rise, with the volume unable to change.
