What are objects composed of?
Matter. Matter is made of tiny particles, and the particles are the smallest units of a substance – an atom and sometimes a group of atoms known as molecules.
82
What are the two types of properties of matters called?
Physical and chemical properties
83
What are the properties of matter?
Matter has strength, thermal and electrical conductivity, brittleness, malleability and ductility, magnetism and non-magnetism, density, and melting and boiling points.
84
TRUE/FALSE: The strength of substance is the ability of matter to stand up to someone's muscular strength by fighting back.
FALSE. It is the ability of matter to stand up to forces being applied without bending, shattering or deforming in any way.
85
TRUE/FALSE: Thermal conductivity is the ability to transfer thermal energy or heat with a special metallic spoon for eating.
FALSE. Thermal conductivity is the ability to transfer thermal energy or heat from one point or place to another.
86
TRUE/FALSE: Brittleness, malleability and ductility refers to the ability of a substance to break or shatter easily, the ability to be shaped or hammered into a thin sheet or to be reshaped in all directions without cracking, and the ability to be drawn into a thin wire.
TRUE. Brittleness, malleability, and ductility does refer to the ability of a substance to break or shatter easily, the ability to be shaped or hammered into a thin sheet or to be reshaped in all directions without cracking, and the ability to be drawn into a thin wire.
87
Explain the non-magnetic and magnetic properties in matter.
Magnetic refers to a material that is attracted by a magnet, while non-magnetic means that the material is not attracted by a magnet.
88
Define density.
Density is the amount of matter in a given space or volume.
89
The melting point of a substance is the temperature at which the solid form of the substance becomes a liquid and the boiling point is the temperature at which a liquid becomes a gas. Is this confirmable?
Yes, this fact is able to be proving as true.
90
What are two kinds of substances?
Pure substances and mixtures.
