What happens to the temperature when a substance is melting?
For most substances, it's the same temperature. For example, ice melts at 0°C (273K), and water freezes also at 0°C. A few substances, such as agar, have a hysteresis. For example, agar melts at 85°C; to solidify it again, you have to cool it down to about 32-40°C.
The temperature at which a solid becomes a liquid is called the what?
Simply, the melting point. Think of an ice cube. The melting point is the temperature at which the ice cube MELTS into a liquid.
What does MP stand for in chemistry?
MP usually stands for Melting Point, i.e. the temperature at which a substance turns from a solid to a liquid.
What is the scientific of saying melting?
The transformation from a solid to a liquid.
Does a substances temperature change when it is changing state?
No. During a phase change, a substance will remain at a constant temperature until the change is complete. In the case of melting ice, the heat initially goes into separating water molecules from the ice lattice, which is melting. During that time, the heat goes into continued melting of the ice and the temperature remains constant. Once all of the ice is melted, adding additional heat will increase the temperature of the now liquid water.
How can you determine if a substances is a solid at room temperature?
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
What kind of substance is a melting point?
what the heck are you asking? the melting point is not a substance. it's a temperature in which the substance starts to melt
What is the melting temperature of a substance?
This is the definition of the melting point of an element or substance. The melting point is when a solid begins to turn into a liquid. A substance also has a boiling point and freezing point.
What two factors determine if a substance will be a liquid?
The temperature of the environment and the melting and evaporation temperature of the substance.
How is the melting point of a substance defined?
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
How is the melting point of substance defined?
= temperature at which (all of) a (pure) substance is melting: going from solid into liquid phase.
What is the temperature called at which a substance changes from a solid to a liquid?
It is the melting point of the substance.
How is the melting point of a substance related to its melting point?
Both indicate the temperature at which the solid and liquid states of a substance are in equilibrium.
What is the melting point of Celsius?
Celsius is a measure of temperature not a substance, and therefore it has no melting point. What is the melting point of what material in Celsius? [You haven't named the substance you want the melting point of/for]
The temperature at which a substance freezes is lower than the temperature at which it melts?
Correct, the temperature at which a substance freezes is lower than the melting point.
What is the temperature at which a substance change from a solid into a liquid?
This temperature is called melting point and is different for each substance or material.
What physical state is silver at melting temperature?
Any pure substance, including silver, at melting temperature can be either liquid, solid, or both. That is the defining characteristic of the melting temperature.
