3. a)Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). ... If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies
b.Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). ... If something is in a solid state of matter, it has a definite shape and volume. The volume of an object is the amount of space it occupies
c.Matter is anything that has mass and takes up space. Mass gives an object the property of weight and inertia (resistance to change in the motion of an object). There are four states of matter, solid, liquid, gas, and plasma. If something is in a solid state of matter, it has a definite shape and volume.
4.Some physical characteristics of matter are shape, color, size, and temperature. An important physical property is the phase (or state) of matter. The three fundamental phases of matter are solid, liquid, and gas (Figure 1.2. 1).
5.According to science atom is the smallest unit of an element that can or cannot exist freely. While on the other hand, a molecule is a set of atoms that are held together with the help of a bond and is the smallest unit of a compound. ... Moreover, an atom contains a nucleus (made up of neutrons and protons) and electrons.
6.The only difference between a molecule of a compound and a molecule of an element is that in a molecule of an element, all the atoms are the same. For example, in a molecule of water (a compound), there is one oxygen atom and two hydrogen atoms. ... Ethane is a molecule with 2 carbon atoms and 6 hydrogen atoms.
