Heat and temperature – Odd one out

The video tutorial explores how different materials change shape, focusing on making glass, lighting a candle, and molding metal, all of which require heat. It identifies crushing a can as the odd one out because it does not involve heat to change shape.

Which of the following processes involves changing the shape of a material?

• Making glass

• Reading a book

• Watching TV

• Listening to music

What makes crushing a can different from the other processes discussed?

• It is a chemical change

• It is more expensive

• It requires more time

• It does not involve heat

Which process does not require heat to change the shape of the material?

• Making glass

• Crushing a can

• Lighting a candle

• Molding metal

What is a common factor in changing the shape of materials like glass and metal?

• Pressure

• Heat

• Electricity

• Water

Why is heat important in processes like molding metal?

• It makes the material heavier

• It allows the material to change shape

• It changes the color

• It speeds up the process
