Weight of an object in a flying airplane will lessen very, very, very slightly due to being farther from the center of the earth (gravity), but its mass remains constant.
They are not the same. Density is a property of matter, namely what it weights per unit volume. E.g., the matter water weights about 1 g per cm^3.
Some laws involved in changes of matter are the Law of Conservation of Matter and the Law of Conservation of Energy. Changes in matter include physical and chemical changes.
its a movement of small particles of matter
The branch of physical science studies the properties of matter and changes in matter is known as chemistry. This is a branch which is mainly concerned with atoms and molecules and how they interact.
This is chemistry.

The study of matter and the changes
The study of properties of matter and how it changes is called chemistry.
The brand of exercise weights does not really matter. The thing you need to take into consideration is the size of the weights that you plan to purchase.
Chemistry - the study of the properties of matter and how matter changes
Some laws involved in changes of matter are the Law of Conservation of Matter and the Law of Conservation of Energy. Changes in matter include physical and chemical changes.
laws and principle governing changes of matter
Matter changes state because of pressure and temperature.
they are all made of matter.. :)
no
Yes because an airplane wing has to cut through wind and create loft and lift.
Changes in the states of matter - or phase changes - do entail changes in volume.
