Why do gases have neither a fixed shape nor a fixed volume ?

Why do gases have neither a definite shape nor a definite volume ?

A substance has neither a fixed shape nor a fixed volume. State whether it is a solid, a liquid or a gas

Answer the following question : Gases have neither a definite shape nor a definite volume. Explain.

State whether the following statements are True or False. If false give the correct statement. Gases have neither a definite shape nor a definite volume.

The substance X normally exists in a physical state which can flow easily but does not fill its vessel completely. It also turns anhydrous copper sulphate blue. When substance X is cooled excessively, it changes into a substance Y which has a fixed shape as well as a fixed volume. If, however, the substance X is heated strongly, it changes into a substance Z which has neither a fixed shape nor a fixed volume. (a) Name the substances X. (b) What is the process of conversion of X into Y known as ? (c ) At which temperature X gets converted into Y ? (d) What is the process of conversion of X into Z known as ? (e ) At which temperture X gets converted into Z ?

The substance 'X' normally exist in a physical state which ca flow easily but does not fill its vessel completely. It also turns dry copper sulphate to blue. When substance'X. is cooled excessively, It changes into a substance'y' which has a fixed shape and fixed volume. If, the substance 'x' is heated strongly., it changes into substance'z' which has neither a fixed shape not a fixed volume. At which temprerature 'x' gets converted into'z' ?
