A jar filled partially with water has an object floating in it. The jar is open. Now, if the jar is closed and a vacuum pump is used to pump the air out, what will happen to the floating object? will it rise up more or sink or ...? and why?

Adding to this, all the heat from boiling would tranfer to the jar and eventually out into the enviroment
