What happends at the melting point?
The melting point of a solid chemically pure substance is a temperature at which the substance can change from a solid to a liquid phase by absorbing heat, called the "heat of fusion", without any change in the internal temperature of the substance. At any specified ambient pressure, there is only one such temperature for each pure substance.
At what temperature does a liquid turn to gas?
If any liquid gets hot enough, it will turn into gas. The point that it turns into gas varies for each substance.
How is the freezing point of a substance related to the melting point of the substance?
The freezing point and melting point of a substance are the same temperature but represent opposite phase transitions. The freezing point is the temperature at which a liquid turns into a solid, while the melting point is the temperature at which a solid turns into a liquid.
What do you call a soild that turns into a liquid and then into a soild again?
WATER! If you put water in a cup and leave it in the freezer it will turn to an ice cube then if you leave it somewhere warm and cosy it will turn back to a liquid again. Try it for yourself even.
What is the temperature of a substance when it turns into another state of matter?
The temperature at which a substance changes state is called its melting point or boiling point, depending on the transition. For example, when a solid turns into a liquid, it reaches its melting point; when a liquid turns into a gas, it reaches its boiling point.
What is the point at which a soild turns into a liquid?
mommy
When a solid turns into a liquid?
When a solid turns into a liquid, the substance has melted.
What happens to a substance during chenges between solid and liguid?
Substances changing between soild and liquid undergo Phase Transition and solids absorb energy at constasnt tempertature to phase change solids to liquid. The reverse happens when the liquid turns to solid, energy is given off.
What do the continents lie on?
My year 7 Geography teacher told mt that under the continents there is a substance like a soild-liquid. It is soild under preaseure and it the preasure is released then it turns to a liquid.I don't know for sure, because I am twelve, but I would think that currently this solid-liquid would be a soilid because the average specific gravity of continents is 2.7 and once a gain, I don't know if that is heavy and putting alot of preassure on this solid-liquid or not.
what is the name for changing from a liquid to a soild?
Freezing.
What substance can be converted from liquid to solid and can not be converted back to liquid?
There is no such substance. Because only a transformation of physical state is taking place. Let me expand: Every substance has a specific temperature at which it changes its physical state. The temp. at which the substance turns into liquid is known as melting point and the temp. at which the liquid turns to solid is known as freezing point. Usually the melting point and the freezing points of a substance are the same. (But there are certain exeptions to this rule.) So if the temperature at which the substance turns into liquid is acheived i.e the melting point - then it definitely would become liquid again.
What happends at the melting point?
The melting point of a solid chemically pure substance is a temperature at which the substance can change from a solid to a liquid phase by absorbing heat, called the "heat of fusion", without any change in the internal temperature of the substance. At any specified ambient pressure, there is only one such temperature for each pure substance.
What is temperature at which a liquid turns to a gas?
the temperature at which a substance in the liquid state becomes a gas is a boiling point
How do you condensation and evaporation differ?
evaporation is when liquid gets hot and turns into steam condensation is wen liquid gets cold and turns into a fog like substance
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.
At what temperature does a liquid turn to gas?
If any liquid gets hot enough, it will turn into gas. The point that it turns into gas varies for each substance.
How is the freezing point of a substance related to the melting point of the substance?
The freezing point and melting point of a substance are the same temperature but represent opposite phase transitions. The freezing point is the temperature at which a liquid turns into a solid, while the melting point is the temperature at which a solid turns into a liquid.
