PS.5.1.3 (5.P.3.2) #3 Schoolnet (Conductors/Insulators)

Front

What is a conductor?

Back

A conductor is a material that allows heat or electricity to flow through it easily, such as metals like copper and aluminum.

Front

What is an insulator?

Back

An insulator is a material that does not allow heat or electricity to flow through it easily, such as rubber, plastic, and glass.

Front

Why is plastic used for water bottles on hot days?

Back

Plastic is used because it does not easily conduct heat, keeping the water cooler for longer.

Front

What happens to glass when it is heated?

Back

When glass is heated, it melts and becomes more flexible, allowing it to be shaped into different forms.

Front

What is the effect of color on heat absorption?

Back

Dark colors, like black, absorb more heat, while light colors, like white, reflect heat.

Front

Why do blacksmiths heat iron before shaping it?

Back

Heating iron makes it softer, allowing it to be shaped more easily.

Front

What is the best material for bike grips in a sunny area?

Back

White rubber is best because it reflects heat and does not heat up quickly.

Front

How does metal behave in terms of heat conduction?

Back

Metal is a good conductor of heat, meaning it can transfer heat quickly.

Front

What is the purpose of a cooler?

Back

A cooler is designed to keep items cold by using insulating materials that do not conduct heat easily.

Front

What is the relationship between heat and flexibility in materials?

Back

Heating materials often increases their flexibility, making them easier to shape.
