the melting point
I think it is the melting point
Plus: Water is liquid and liquid is melting
Answer: Melting Point
At mercury's own freezing temperature, the mercury can be either solid or liquid; that is the definition of "freezing temperature".
I think one of the factors is temperature as an example water, H2at 0 0c and below, the state of matter of water is solid, we call as ice cubed at the 0 0c too, then the ice start to melt.. and at room temperature the state of matter of water is completely become a liquid. At high temperature such as boiling point at 1000 c and above molecule of water start to change from liquid to gas.
Then particles are speeded up so they come in a higher 'state of matter', meaning: solids start melting, liquids start evaporating. Volume expands and/or pressure increases.
If you mean the "state" of matter, during evaporation, it changes from a liquid to a gas.
There is no such temperature to start evaporating. Even in the room temperature or in a refrigerator, water does evaporate. When a particular water molecule absorbs adequate energy (let's say from heat), there will be a phasechange in that molecule from liquid to gas, and it's called evaporation.
Most solids expand as they increase in temperature and contract as they get colder. Interestingly, water after it freezes will start to expand as it gets even colder.
Solids become liquids when the temperature reaches melting point, groups of particles start to brake away from each other. This is when the solid starts becoming a liquid. Liquids become solids on cooling, the particles move slower and become a solid.
0 degrees centigrade is the melting/freezing point for water
When we start heating an object, whether solid, liquid or gas, it's molecules start vibrating faster about a fixed point. They gather enough kinetic energy (due to the heat) to break free from their original state and start evaporating (in case of liquids). Since the molecules start vibrating faster, more intermolecular space occurs in between the molecules of the object. Thus, the solubility of the liquid INCREASES.
as heat is removed from the refrigerant at the condenser it reach it saturated temperature n then it'll start to flash change state to a high pressure liquid LBMDOLPH-CHECKMATE on soundcloud
Yes. A solid can change shape. The process is called melting. Each solid has a melting point. Ice has a melting point of 0 degrees Celcius. You should learn this when you are in Grade 6 or 7. But let me tell you 1 thing, some solids like wood do not melt, wood burns when the temperature is too hot. The only type of solids that can melt are the type of solids that have the properties of changing into a liquid. You can search up videos in Youtube for more information about solids. You can type in "Ice melting", that would be a simple thing to start with.add. And solids may have their shape altered by applying an external force. That is how a metal can is formed, or a railway iron, or a copper wire, or a metal spoon. Other solids such as wood and plastic may be similarly deformed.
Liquid changes to gas when pressure is reduced and temperature is increased. When pressure on liquid is reduced, the inter molecular space increases and temperature increases the kinetic energy of the atoms. This changes liquid to gaseous state
For the solubility of solids in liquids and liquids in liquids, mainly,when the temperature increases, the solubililty increases. But in some compounds the solubility decreases with the temperature, such as NH3 and SO2 In the solution of gases in liquids,increase in temperature results to decrease in the solubility of gases.This is the reason why bubbles appear when tap water is heated.Increase in temperature allows the gas molecules to escape from the water molecules in the form of bubbles.The same explanation is applied to softdrinks which form bubbles as they warm up. These bubbles that you are seeing is like when you stir in too much koolaid powder into a glass of water, and soem settles to the bottom. When the water is heated, the amount of solute that can be dissolved in the liquid decreases, thus it does not have enough room to keep all of the CO2 gas in the liquid. The CO2 gas escapes into the air and is not noticable to the human eye.

Liquids, solids and gasses EXPAND when heated- the particles occupy more space.
Assuming you put a bowl of ice cubes into the fridge (which is well isolated, but the temperatue is above freezing level). The ice will begin to melt. Even if you turn the fridge off, the temperature in the fridge will drop as the ice takes up energy from the surrounding air to liquify. The answer is: Yes.
Latent heat of vapourisation can be define as the rate by which water is heat to vapourise, it has a difference with evaporation because evaporation occurs directly when the water start heatin while vapourisation always start in a specific temperature
