Ice can be melted at a temperature below 0°C by applying pressure. The process is an example of a?
Answer: Spontaneous physical change
Explanation
Melting ice below 0°C by applying pressure is a spontaneous physical change.
Physical change:
This is correct because the process only changes the state of water from solid to liquid, without altering its chemical composition.
Spontaneous:
- Under the applied pressure, the ice will naturally melt even below 0°C.
- A spontaneous process occurs without any external energy input.
