In a solid the particles are all really close together and stuck like that. As the solid melts and becomes a liquid the particles spread out. A solid won’t easily change its shape because the particles are bound together but in a liquid the shape is more fluid, take water when you pour it into a container it will change to fit the shape of a container this is because the particles aren’t as close and can move around. The particles of a solid change when it melts because it is changing states to a liquid.
Metals consist of giant structure of atoms arranged in a regular pattern. The electrons in the outer shell of metal atoms are shared , and are free to move throughout the structure. Therefore the structure is formed by positive charged metal ions held together by a 'sea' of delocalised.
3:6:2 is the correct answer
When collecting gas over water, the gas is always a mixture of the gas collected and water vapor. This statement is true.
The gaseous phase of water is known as water vapor or aqueous vapor. Within the hydrosphere, it is one type of water state. Water vapor can be created by the boiling or evaporation of liquid water as well as by the sublimation of ice. Like the majority of other atmospheric elements, water vapor is transparent. The mist that hovers above a saucepan of boiling water is an illustration of water vapor.
Gaseous water, particularly when it is distributed in the atmosphere. Steam. The most frequent greenhouse gas is water vapor. It contributes to around half of the planet's warming. It absorbs heat that is projected upward from the earth while letting practically all sunlight reach the planet's surface like other greenhouse gases do.

Answer:
Ur answer is C. Their average kinetic energy
Explanation:
In chemistry, we define the temperature of a substance as the average kinetic energy of all the atoms or molecules of that substance. Not all of the particles of a substance have the same kinetic energy. ... It is the average kinetic energy of the particles that thermometers measure and we record as the temperature.
