Q

At what temperature is the mixture for glass heated?

A

1000°C

This high temperature allows the mixture to become fluid for shaping.

19
Q

What can be added to the glass mixture to alter its properties?

A

Other materials to give color or special qualities

This customization allows for various uses, such as in bottles and fiber-optic strands.

20
Q

Fill in the blank: The process of turning fluids into solids is facilitated by their ability to _______.

A

Take the shape of containers

21
Q

True or False: Slurries can be used to wash off mud or sand from surfaces.

22
Q

What is the primary composition of steel?

A

A mixture of iron, carbon, and small quantities of other substances.

23
Q

At what temperature is steel heated to melt the mixture?

24
Q

What happens to fluid steel after it is shaped?

A

It is allowed to cool.

25
What is an example of a fluid that carries other materials?
Toothpaste.
26
What powdered material is commonly found in toothpaste?
Bauxite.
27
What is the purpose of the detergent in toothpaste?
To clean your teeth.
28
What substance is added to toothpaste to strengthen teeth?
Fluoride.
29
