The pressure of a sample of helium in a 1.00 L container is0.988 atm what is the new pressure if the sample is placed in a 2.00L container

Iwould you figure it out but you don't have a picture or in your question as to what the physical property you're looking for is

Where are the following questions

Non metal is an element or substance that is not a metal metal is a solid material that is typically hard, shiny, malleable, fusible, and ductile, with good electrical and thermal conductivitymetalloid is an element (e.g., germanium or silicon) whose properties are intermediate between those of metals and solid nonmetals. they are electrical semiconductors.

Yeah, but what are you trying to ask?
