Question

Give reasons :-

(i) A gas cylinder cannot be half filled

(ii) CO2 is a gas

Answer 1

A gas can't be half filled because the molecules of gas don't come close like the solids. They always have a tendency to be filled up in a container. A gas cylinder cannot be half filledbecause of the following reasons: ...Gases are the fluid form of matter which occupy the entire container

Answer 2

1) A gas can't be half filled because the molecules of gas don't come close like the solids. They always have a tendency to be filled up in a container. A gas cylinder cannot be half filled because of the following reasons: ... Gases are the fluid form of matter which occupy the entire container.
2) CO2 consists of individual molecules with one central carbon atom double bonded to two oxygen atoms. Silicon does not form double bonds with oxygen. co2 is gas but sio2is solid because the sio2 is in giant molecular structure but the co2 is simple molecular structure.because of this reason co2 is gas but sio2 is solid.
