What substance become a liquid when his temperature is above 0 degrees Celsius?
Any substance with a melting point above this given temperature.
What are the similarities for freezing and melting?
Both freezing and melting involve a change in the state of matter from solid to liquid or liquid to solid, respectively. The temperature at which freezing and melting occur is the same for a given substance, known as the freezing/melting point. During both processes, energy in the form of heat is either released (freezing) or absorbed (melting).
Why are the melting point and boiling point of the same matter different?
Boiling point is the temperature at which a substance turns into a gas, while melting point is the temperature at which a substance turns into a liquid state from a solid state. The boiling point is always a higher temperature then the melting point. The melting point has a substance turn into a liquid from solid, and boiling point has a liquid turn into a gas.
At a given temperature and pressure the physical state of a substance is determined by?
It's determined by the spacing of its atoms. If they are spaced close together in a rigid formation it's a solid. Somewhat spread out and fluid in formation is a liquid. Spaced far and very active in its motion is a gas.
The amount of heat gained or lost by a substance is equal to the product of?
mass times the temperature change rimes specific heat capactiy
What is the temperature at which a given substance will change from a solid into a liquid?
The temperature at which a substance changes from a solid to a liquid is called its melting point. It is a specific temperature unique to each substance and is determined by the intermolecular forces within the substance. When the substance reaches its melting point, the solid will begin to transition into a liquid state.
What substance become a liquid when his temperature is above 0 degrees Celsius?
Any substance with a melting point above this given temperature.
What is the name given to heat energy at melting point?
The heat energy required to change a substance between solid & liquid at constant temperature is called the "latent heat of fusion". If the change is from solid to liquid the substance gains this energy. If the change is from liquid to solid the substance gives up this energy. The exact amount of latent heat of fusion is different for different substances.
What is the name given to the change in state from gas to liquid?
When a substance is liquid and it changes to gas, we call that boiling.
What is the saturation temperature and how does it relate to the properties of a substance?
The saturation temperature is the temperature at which a substance changes from a liquid to a gas or from a gas to a liquid. It is a key property that helps determine the state of a substance at a given pressure. The saturation temperature is important in understanding the behavior of substances in various processes, such as boiling or condensation.
What is the heat of evaporation?
The heat of evaporation, also known as latent heat of vaporization, is the amount of energy required to change a substance from liquid to gas at its boiling point without changing its temperature. This energy is used to overcome the intermolecular forces holding the liquid together.
Boiling point melting point and density are some of an elements what?
Boiling point is the temperature at which a substance changes from a liquid to a gas, melting point is the temperature at which a substance changes from a solid to a liquid, and density is a measure of how much mass is contained in a given volume of a substance.
How is elements related to physical change?
Well, if you were for example discussing the the physical change of substance from one state to another, eg. Ice to liquid water than the relation to physics concerns energy. When discussing temperature change what you are in reality dealing with is how much energy a given substance or object contains.
How do you know that particles in a gas have more energy than particles of same substance as a liquid or a solid?
We know that for any given substance, and at a given pressure, the gas phase exists at a higher temperature than the liquid phase, which exists at a higher temperature than the solid phase. And temperature measures heat energy per molecule or atom, hence, gas particles have more energy than particles of the same substance in their liquid or solid phase.
Under what conditions heat can be given to a substance without raising its temperature?
If the substance is in solid condition and at the melting temperature, heat can be given without rising the temperature. Then the substance melts and all the heat will be used in the melting process. Also when the substance is at the boiling temperature you can add heat without rising the temperature. At that point the heat is used to vaporate the substance.
