How are liquids formed?
Liquids are formed when a substance's molecules have enough energy to move around and flow freely, but not enough to overcome the attractive forces that hold them close together, as in a solid. The arrangement and movement of molecules in liquids give them a definite volume but not a definite shape. Heating a solid or cooling a gas can cause them to change into a liquid state.
When liquids are exposed air?
When liquids are exposed to air, they can evaporate due to the molecules in the liquid gaining enough energy to break free from the surface and enter the air as gas. This process is known as evaporation. The rate of evaporation can be influenced by factors such as temperature, surface area, and humidity.
How does the vapor pressure of a substance change with temperature?
The vapor pressure of a substance increases with temperature. As the temperature rises, more molecules have enough energy to escape from the liquid phase and enter the gas phase, leading to an increase in vapor pressure.
What is a substance that will change from a soild into a liquid?
A substance that will change from a solid to a liquid is called a melting substance. This process is known as melting, where the solid substance absorbs heat energy and transitions into a liquid state.
When liquids change to gas they?
undergo evaporation, during which the molecules gain enough energy to break free from the liquid phase and enter the gaseous state. This process occurs at the surface of the liquid, as molecules escape into the air as vapor.
Is there enough energy on air at room temperature to change some liquids to gases?
Yes.
Can there be enough energy in air at room temperature to change some liquids to gases?
Yes - including water, which is why it evaporates.
Is there enough energy in air at room temperature to change some liquids to gases?
Observation in air filed rooms at normal temperature indicates that water, alcohol, hydrocarbons and Mercury all evaporate (change to a gas) when exposed to that air. The energy required must come from somewhere, that source is the heat energy contained in the air.
What happens to all gases many liquids and most solids when their temperature increases?
When the temperature of gases, many liquids, and most solids increases, their particles gain kinetic energy and move more vigorously. For gases, this often leads to an increase in pressure if the volume is constant, while liquids may expand slightly. Solids generally do not change their volume significantly, but they can become more malleable or change phase if the temperature is high enough. Overall, increased temperature typically results in expansion and changes in state or behavior.
What liquids will evaporate?
All liquids would evaporate if heated to a high enough temperature.
The temperature at which a liquid has gained enough heat energy to change to a gas?
Its boiling point.
Why liquid freeze?
Liquids freeze because the particles have less energy so therefore becoming solid because the cannot spread as far apart. Liquids freeze when their particles have slowed down enough to "stick" together and form a solid structure. When the temperature--the average speed of particles--is low enough, liquids freeze into solids.
What are solids that can turn into liquids?
All solid can be liquified if the temperature is high enough.
What happens when it releases enough energy?
When an object releases enough energy, it can result in various outcomes depending on the context. For example, in the case of a nuclear reaction, a significant release of energy can lead to an explosion. In a chemical reaction, releasing enough energy can cause a change in temperature or the formation of new substances.

What is the phase change when a solid becomes a liquid?
Gases become liquids when they have less space to occupy or when the temperature is cool enough for that substance to be a liquid. Take water as an example. When the temperature is hot enough, it is steam. As the temperature cools, the molecules loose energy and begin sticking together forming liquid water. As the temperature drops farther, the water turns into a solid. The temperature at which a gas becomes solid varies by the gas. Dry ice is the solid form of carbon dioxide that is normally a gas.
Do liquids turn into solids?
When a liquid looses enough energy (heat), it turns into a solid.
