Worksheet Overview

QUESTION 1 of 10

The images below show some ceramic objects. Glass is another example of ceramic materials.

 

 

Most ceramics are compounds of metal and non-metal elements, for example oxides. They are insulators, which means no electricity or heat can go through them, so they can withstand high temperatures and harsh conditions. Therefore, they do not corrode easily. They are not as tough as metals and most of them are not malleable, which means they cannot be reshaped easily. 

 

Polymers is the scientific name for plastic materials. They are large molecular structures (see diagram below), made of carbon and hydrogen. They have low density (so are light weight) and are unstable in high temperatures. This means they have a low melting point and are much less strong than metals.

 

 

They can be easily formed into different shapes and the cost of manufacture is relatively low. The properties of polymers make them the preferred material for many applications.

 

Composites are made of two or more materials with different properties. The different materials keep their properties as they are not merged with each other, but the combination of their properties makes them really useful. For example, fiberglass is a composite of a polymer and glass. Concrete is another example of composites.

Choose an example of ceramic materials.

glass

fiberglass

CORRECT ANSWER
metal
EDDIE SAYS
Ceramics are compounds of metal and non-metal materials.
  • Question 3

Is this statement true or false?

Ceramics are good conductors of heat and electricity.

CORRECT ANSWER
false
EDDIE SAYS
The statement is false; ceramics are insulators of heat and electricity.
  • Question 4

Can ceramics be reshaped easily?

CORRECT ANSWER
no
EDDIE SAYS
No, ceramics are not malleable, which means they cannot be reshaped easily.

What do you know about the density of polymers?

CORRECT ANSWER
It is low.
EDDIE SAYS
Polymers have a low density.
  • Question 9

Why are composites made of two or more materials?

CORRECT ANSWER
The properties combined make composites more useful.
EDDIE SAYS
The combined properties in composites make them more useful materials.
