Changes of State

Which of the following describes the process of freezing?

• Freezing occurs when the temperature of a substance drops to zero degrees Celsius.
• Freezing occurs when the particles of a solid vibrate so fast that they break free.
• Freezing occurs when the temperature drops enough that a gas turns into a solid.
• Freezing occurs when the particles in a liquid slow down and take fixed positions.
