Particles in the gas are in a state of rapid and random motion because of their high kinetic energy content. This explains why they are spaced so far apart too.
Particles in a liquid have higher attractive forces towards each other but lower internal kinetic energy. This brings the particles closer together.
Particles in a solid have the least kinetic energy and the highest interatomic/intermolecular attractive forces (except for substances that sublime). This makes them stick together.
Cooling a gas condenses it to a liquid by removing energy from it. Cooling a liquid even further removes even more energy from it. The particles come closer together and a solid is formed.
What else can I help you with?
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
What is a kind of energy involved in phase change?
Thermal energy, when you heat a solid, it turns to liquid and with more heat it will turn to gas
When a solid turns to liquid energy is absorbed?
When a solid turns to liquid, it absorbs energy in the form of heat. This heat causes the solid's particles to gain enough energy to break free from their fixed positions and move more freely, transitioning them into a liquid state.
What is the change when a liquid turns to a solid?
When a liquid turns into a solid, the molecules slow down and come closer together, forming a more ordered and structured arrangement known as a crystalline structure. This change releases energy in the form of heat.
When solid turns to liquid the amount of heat energy in the object is?
When a solid turns to liquid, the amount of heat energy in the object increases. This process, known as melting, requires the absorption of heat energy, which breaks the bonds holding the solid's particles together. As energy is added, the temperature of the solid rises until it reaches its melting point, at which point it transforms into a liquid without a change in temperature until the entire solid has melted.
What change takes place when a solid changes directly to a solid?
Sublimitatition IS WHEN A SOLID TURNS DIRECTLY INTO A GAS! DEPOSITION IS WHEN A GAS TURNS DIRECTLY INTO A SOLID!
What is change of state from liquid to solid?
It is called melting when a solid turns into a liquid
The change in state in which a liquid turns into a solid?
"freezing"
What is the state of change from liquid to solid?
It is called melting when a solid turns into a liquid
What is the physical change of a solid at the melting point?
It turns from a solid to a liquid
What physical change occurs to water when it is frozen?
it turns into a solid
How do you know that you have a new substance after a chemical change?
it turns into a solid
