Sublimation.
The phase change from a gas directly to a solid is called deposition. This occurs when a gas loses enough energy to transition into a solid state without passing through the liquid phase.
Yes, ice melting is a physical change.
To change from solid to liquid, a substance needs to absorb heat energy to weaken the intermolecular forces holding its particles together. This process is known as melting or fusion. The temperature at which this change occurs is called the melting point.
The change from gas directly to solid is called deposition. It occurs when a substance transitions from the gaseous state to the solid state without passing through the liquid state.
The phase change from solid to liquid is melting. This process occurs when heat is added to a solid substance, causing its particles to gain enough energy to overcome their fixed positions and transition into a more disordered, liquid state. The temperature at which this phase change occurs is known as the melting point.
A change of solid occurs during both freezing and melting.
The phase change from a gas directly to a solid is called deposition. This occurs when a gas loses enough energy to transition into a solid state without passing through the liquid phase.
A change in temperature occurs during both freezing and melting. Freezing and melting are physical changes since the chemical contents of the matter do not change.
Sublimation is the process where a solid turns directly into a gas without passing through the liquid phase, while melting is the process where a solid turns into a liquid upon the addition of heat. Sublimation occurs at specific temperatures and pressures where the solid phase is not stable, whereas melting occurs at the melting point of a substance.

Yes, ice melting is a physical change.
Sublimation of water in nature happens when ice or snow turns directly into water vapor without melting into liquid water first. This occurs when the temperature and pressure are just right for the solid ice to change into gas without becoming liquid water.

Yes, carbon dioxide can undergo sublimation, which is the process of transitioning directly from a solid to a gas without passing through the liquid state. This typically occurs at pressures below atmospheric pressure.
Shortening melting is a physical change. It occurs when the heat causes the molecules in the shortening to become more energetic, changing from a solid to a liquid state, without altering the chemical composition of the shortening.
