What is the name of the process where a solid becomes a liquid?

• Freezing

• Melting

• Vaporization

• Condensation

• Sublimation

Answer explanation

The process where a solid becomes a liquid is called melting. During melting, heat is added to the solid, causing its particles to gain energy and transition into the liquid state.

What is the name of the process where a gas becomes a liquid?

• Freezing

• Melting

• Vaporization

• Condensation

• Sublimation

Answer explanation

The process where a gas becomes a liquid is called condensation. This occurs when gas molecules lose energy and come together to form a liquid, contrasting with vaporization, which is the transition from liquid to gas.

What is the name of the process where a solid becomes a gas?

• Freezing

• Melting

• Vaporization

• Condensation

• Sublimation

Answer explanation

The process where a solid becomes a gas without passing through the liquid state is called sublimation. Examples include dry ice turning into carbon dioxide gas.

What is the name of the process where a liquid becomes a gas?

• Freezing

• Melting

• Vaporization

• Condensation

• Sublimation

Answer explanation

The process where a liquid becomes a gas is called vaporization. This occurs when the molecules in a liquid gain enough energy to overcome intermolecular forces and enter the gas phase.

What is the name of the process where a liquid becomes a solid?

• Freezing

• Melting

• Vaporization

• Condensation

• Sublimation

Answer explanation

The process where a liquid becomes a solid is called freezing. During freezing, the temperature drops, causing the molecules in the liquid to slow down and arrange into a solid structure.

What is the name of the process where a gas becomes a solid?

• Freezing

• Melting

• Vaporization

• Deposition

• Sublimation

Answer explanation

The process where a gas becomes a solid is called deposition. This occurs when gas particles lose energy and transition directly into a solid state, bypassing the liquid phase.
