Mass is the weight of an object.

In common usage, the mass of an object is often referred to as its weight, though these are in fact different concepts and quantities. In scientific contexts, mass is the amount of "matter" in an object (though "matter" may be difficult to define), whereas weight is the force exerted on an object by gravity.

Solubility and melting point are two examples of physical properties.

Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, freezing points, melting points, and boiling points. Freezing point is the temperature at which a liquid changes to solid. Melting point is the temperature at which a solid is converted to a liquid.

Atoms that make up a compound are bonded together; they cannot be separated by physical means.

When atoms from different elements are joined together in groups, they form molecules. The atoms in molecules bind together chemically, which means that the atoms cannot be separated again by physical means, such as filtration. The molecule has different properties from the elements from which is was made.

The density of an object can be calculated by dividing the object’s length by its width.

The density of an object can be calculated by dividing the object's mass by its volume. A rectangular prism has a density of 15g/cm3. The prism has a mass of 5,625 g. The length of the object is 5 cm.

A physical property is a characteristic of matter that you cannot observe or measure without changing the identity of the matter.

Physical Property. A physical property is a characteristic of a substance that can be observed or measured without changing the identity of the substance. ... Physical properties of matter include color, hardness, malleability, solubility, electrical conductivity, density, melting points, and boiling points.

Every element and compound has a unique set of properties.

Every element has a unique set of properties that can be used to identify the element. These characteristics are the same no matter what amount of the element is present. These properties include boiling point, melting point, density, and reactivity.

Explanation:

the answer is c. nacl

air

in a tire you fill a tire with air

then a couple days later you check the air pressure in the tire

hope this mark me brainliest
