How does a solid change into a liquid?

A solid changes into a liquid through a process called melting, which occurs when the solid absorbs enough heat energy to break the bonds holding its particles together in a fixed arrangement. As the solid particles gain energy, they start to vibrate more rapidly and move apart from each other, transitioning to a more fluid-like state where they can flow and take the shape of their container, forming a liquid.

What process occurs when a liquid changes into a gas?

The process that occurs when a liquid changes into a gas is called evaporation. During evaporation, molecules in the liquid gain enough energy to break free from their attraction to each other and escape into the gas phase. This process happens at the surface of the liquid, with molecules leaving the liquid and entering the surrounding atmosphere as a gas.

What happens when a gas changes into a liquid?

When a gas changes into a liquid, it undergoes a process called condensation. This occurs when the gas loses energy (heat) and particles slow down, allowing them to come closer together and form intermolecular forces that hold them in a liquid state. As a result, the gas transitions into a liquid state, typically accompanied by a decrease in volume and an increase in density.

What causes a solid to change directly into a gas without becoming a liquid first?

The process of a solid changing directly into a gas without becoming a liquid first is known as sublimation. Sublimation occurs when the solid substance bypasses the liquid phase and goes directly from a solid to a gas under specific conditions, such as low atmospheric pressure or high temperatures. This phenomenon is exemplified by substances like dry ice (solid carbon dioxide) and mothballs (solid naphthalene) undergoing sublimation when exposed to the appropriate environmental factors.

How does a gas change into a solid without becoming a liquid?

Gas can change into a solid without becoming a liquid through a process called deposition, where gas molecules lose energy and transition directly into a solid state. This can occur when the temperature of the gas drops below its sublimation point, causing the gas molecules to slow down and come together to form a solid without passing through the liquid state.

What is the process called when a solid changes directly into a gas without becoming a liquid?

The process of a solid changing directly into a gas without becoming a liquid is called sublimation.

How does a liquid change into a solid?

A liquid changes into a solid through a process called solidification or freezing. This occurs when the temperature of the liquid is lowered to its freezing point, causing the particles to slow down and come closer together, forming a more ordered and rigid structure characteristic of a solid state. As the liquid loses heat energy, its particles lose kinetic energy and align themselves into a fixed position, resulting in a solid state with a defined shape and volume.

What happens when a gas changes directly into a solid?

When a gas changes directly into a solid, the process is known as deposition. During deposition, the gas loses energy and transitions directly into a solid state without passing through the liquid phase. This happens when the temperature of the gas decreases to a point where its particles slow down enough to form a solid structure. Examples of deposition include when water vapor in the air changes into frost or snowflakes without first becoming liquid water.

What is the term for the process of a liquid changing into a gas at the surface of a liquid?

The term for the process of a liquid changing into a gas at the surface of a liquid is called evaporation.

How does a gas change into a liquid at the surface of a liquid?

When a gas changes into a liquid at the surface of a liquid, it goes through a process called condensation. This occurs when the gas molecules lose energy and slow down, coming into contact with the liquid molecules. As the gas molecules lose energy, they lose the ability to overcome the intermolecular forces present in the liquid, causing them to stick together and form a liquid. This transition from gas to liquid at the surface of a liquid is due to the attraction between the gas molecules and the liquid molecules, leading to the formation of a condensed phase.
