Question

everything around you—your desk, your chair, and the people around you—are all made of matter. even things you cannot see, such as air, are made of matter. matter is anything that takes up space and has mass. the mass of an object is the amount of matter the object contains. although all things are made of matter, the kind and amount of matter in each object varies.
consider a spoonful of sodium chloride, otherwise known as table salt. the spoonful of sodium chloride has a certain mass. you can change the mass by adding or removing salt. however, any size sample of sodium chloride will always consist of 39.34% by mass of the element sodium and 60.66% by mass of the element chlorine. if you pour the spoonful of sodium chloride into a glass of water, the mass of salt and the matter have not changed. the salt may dissolve, but the amounts of sodium and chlorine do not change. the idea that matter cannot be created or destroyed is known as the law of conservation of matter, or the law of conservation of mass.
analyze a ball of clay is manipulated into different shapes in each of the images below. does the amount of mass and matter in each of the images below change as the size and shape of the clay ball is changed? explain your reasoning.
physical properties of matter
every substance has characteristic physical and chemical properties that determine its identity. a physical property is a property that can be measured or observed without changing the identity of matter. some recognizable physical properties are shown in figure 1.
collaborate with a partner, make a list of questions you have about the physical properties shown in figure 1. what other characteristics of matter do you think are physical properties?

Explanation:

The law of conservation of matter (or mass) states that matter cannot be created or destroyed. When the clay ball is manipulated into different shapes, no matter is added or removed. The amount of matter (and thus mass) remains the same because it's just a physical change (change in shape, not in the quantity of matter).

Answer:

No, the amount of mass and matter does not change. According to the law of conservation of matter/mass, matter is neither created nor destroyed during a physical change (like changing the shape of the clay). The clay is just reshaped, not losing or gaining any matter.
