Mass cannot be created or destroyed, and will therefore remain constant even when matter changes its state. The volume, on the other hand, can change because volume is a state function (dependent on the state of the system). Mass is an intrinsic property of the system.
Weight and mass are commonly used interchangeably but are actually two different concepts. Weight is the gravitational force acting on a body defined as W=mg, where g is the gravitational constant. On earth, g = 9.81 m/s2, and the correct unit of weight is the Newton. Weight also remains constant with state changes.

Does changes in a state of matter involve a physical change?
A chaqnge of the state of matter is allways a physical change.
What state of matter does not have its own volume or shape?
Liquid, take shape of container in which they are kept.
What is the most common reason for matter changing its state Why?
Heat change and pressure change are the only reasons, but in our atmosphere, more often heat.
How does the start of matter change during evaporation?
If you mean the "state" of matter, during evaporation, it changes from a liquid to a gas.
Which of the following is true about a physical change in matter?
It is something that can be seen, touched, tasted, smelled, or observed in some way.
What state of matter does not change in volume?
Changes in the states of matter - or phase changes - do entail changes in volume.
What state of matter undergoes change in volume most easily?
Gases adapt most easily to changes in volume.
Which state of matter changes volume the easiest?
Liquid
What state of matter changes volume to fill it's container?
gas
What is the change in volume from gaseous air to liquid air?
A change in volume is a change in volume - there is no difference. The question, as asked, is therefore meaningless. However if you try to compress air, its volume will decrease (because the gaseous state of matter is compressible). On the other and if you try and compress a liquid the volume will not change as the liquid state of matter is incompressible (that is why/how hydraulic machines work).
What is the state in which matter changes in both shape and volume?
Gas.
What state of matter undergoes changes in volume easily?
Gas

A liquid.
