Vaporise

The video tutorial explains the endothermic process of vaporization, which requires heat energy. It also covers sublimation, where a material transitions directly from a solid to a vapor, using ice and iodine as examples.

What is required for an endothermic process to occur?

• Input of light energy

• No energy change

• Release of heat energy

• Input of heat energy

Which of the following is an example of a material that can undergo sublimation?

• Water

• Iron

• Ice

• Copper

What is the term for a process where a solid turns directly into vapor?

• Melting

• Sublimation

• Condensation

• Evaporation

Which of the following processes is endothermic?

• Condensation

• Boiling

• Sublimation

• Freezing

In what conditions can iodine undergo sublimation?

• Right conditions

• High pressure

• In a vacuum

• Low temperature
