Sublimation is when a solid turns into a gas without becoming a liquid first.
This happens under certain conditions. Usually, it takes place when the temperature and pressure are lower than what we call the triple point of a substance.
Melting: This is when a solid changes to a liquid. It happens at a specific temperature known as the melting point.
Freezing: This is the opposite of melting. It's when a liquid turns into a solid at the freezing point.
Condensation: This occurs when a gas changes into a liquid. This happens at the condensation point.
Evaporation: This is when a liquid turns into a gas. It can occur at any temperature, not just the boiling point.
A great example of sublimation is dry ice, which is solid carbon dioxide (CO₂). Dry ice starts to turn into gas at a really cold temperature of -78.5 degrees Celsius.
