What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
temperature
What the temperature at which a substance changes from a liquid a gas?
The answer to this question is entirely dependent on the type of substance. This temperature is called the boiling point.
Does the temperature of the atmosphere decrease steadily with increasing altitude?
Yes it does but the rate changes depending on what you come across. But yes, it does decrease.
Has thermal energy been transfered into or out of a substance if the average kinetic energy changes?
Temperature is a measure of the average KE of the PARTICLES of a substance. So if the temperature changes, ave KE changes, thus thermal energy will have been transferred.
What is the purpose of a thermobarometer in a volumeter?
A thermobarometer in a volumeter is used to measure both temperature and pressure, which are important factors in determining the volume of a substance. By taking into account temperature and pressure, the volumeter can accurately calculate the volume of the substance being measured.
When a substance changes state what happens to its thermal energy?
Changes the temperature of the substance
What substance is the temperature at which it changes from a solid to a liiquid?
The temperature at which a solid changes to a liquid is the melting point.
What changes during melting?
The substance absorbs the heat of fusion. The temperature does not go up, but the form of the substance changes.
What is the temperature called at which a substance changes from a solid to a liquid?
It is the melting point of the substance.
What happens to a temperature of a substance while a changing of state occurs?
As a substance changes state, the temperature remains constant.
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
temperature
What is the temperature at which a solid changes to a liquid is its what point?
The temperature at which a pure solid changes to a liquid is the substance's melting point.
When a substance changes from one state of matter to another it is call?
When a substance changes from one state of matter to another it is called changing its state. Temperature changes are usually the main cause of this change.
The temperature at which a substance changes from a liquid to a solid is named?
This temperature is called freezing point and is different for each substance or material.
The temperature at which a substance changes from a solid to a liquid is calleld what?
This temperature is called melting point and is different for each substance or material.
What the temperature at which a substance changes from a liquid a gas?
The answer to this question is entirely dependent on the type of substance. This temperature is called the boiling point.
