Question

A gas has a ____________ shape that ____________ conform to the container shape, but fills the entire shape and, thus ____________ form an upper surface.

Answer 1

varying, does, does not

Step-by-step explanation:

A gas does not have a defined volume on its own. It takes up the shape of the whatever container it is in.

This is due to the fact that gasses have weak inter-molecular forces between them. Gases are generally compressible unlike liquids which are mostly incompressible. Some, example of gases are hydrogen (H2), nitrogen (N2), oxygen (O2) etc.
