Question 81

What are objects composed of?

Answer 81

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.

Question 82

What are the two types of properties of matters called?

Answer 82

Physical and chemical properties

Question 83

What are the properties of matter?

Answer 83

Matter has strength, thermal and electrical conductivity, brittleness, malleability and ductility, magnetism and non-magnetism, density, and melting and boiling points.

Question 84

TRUE/FALSE: The strength of substance is the ability of matter to stand up to someone’s muscular strength by fighting back.

Answer 84

FALSE. It is the ability of matter to stand up to forces being applied without bending, shattering or deforming in any way.

Question 85

TRUE/FALSE: Thermal conductivity is the ability to transfer thermal energy or heat with a special metallic spoon for eating.

Answer 85

FALSE. Thermal conductivity is the ability to transfer thermal energy or heat from one point or place to another.

Question 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.

Answer 86

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.

Question 87

Explain the non-magnetic and magnetic properties in matter.

Answer 87

Magnetic refers to a material that is attracted by a magnet, while non-magnetic means that the material is not attracted by a magnet.

Question 88
