What is in intensive property of matter?
Intensive properties of matter1. Density -is the mass per unit volume of a material2. Boiling point -temperature at which a liquid starts to boil3. Melting Point -temperature at which solid starts to melt4. Freezing point -temperature at which a liquid changes to solid5. Conductivity -the intensive property of a material that indicates its ability to conduct heat6. Hardness -is the resistance of a material to being scratched by another7. Malleability -is the capability of a material to be hammered into thin sheets8. Ductility -is the capability of a material to be drawn into wires
Which scale is divided into 100 equal parts between the freezing and boling points of water?
Celsius
How many grams equal a teaspoon?
It depends on what substance you are referring to.
What are the various units to measure temperature of substance?
There are really only two units that are widely used to describe temperature: -- the Kelvin/degree Celsius, equal to 1/100 of the difference between water freezing and water boiling; -- the degree Fahrenheit/degree Rankine, equal to 1/180 of the difference between water freezing and water boiling; The Reaumer degree, equal to 1/80 of the difference between water freezing and water boiling, was used in Europe until the late 18th Century. Its only modern use is in the measuring of milk temperature in cheese production. It's used in some Italian dairies making Parmigiano-Reggiano and Grana Padano cheeses and in Swiss Alp cheeses.
What do melting melting point and freezing point have in common?
They have an equal value and are synonyms.
Is freezing point of a substance is equal the melting point of the same substance?
The freezing point and the melting point both refer to the temperature at which a substance changes between a liquid and a solid state. If other conditions remain the same, the temperature at which a substance freezes is the same temperature at which it melts. Water is an every day example with a freezing point of 0C, the same temperature as it will begin to melt. Other substances such as metals have significantly higher melting points from around 200C to more than 3000C.
Can the temperature at which a substance melts is the same temperature at which it changes from liquid to solid?
Yes. Melting point is changing from a solid to liquid & freezing point is changing from a liquid to a solid. Both occur at the same temperature & these terms are usually used interchangably, although melting point is probably used more often than freezing point.
Is the boiling point of something the same as the melting point?
The boiling point is the temperature at which the vapor pressure of the liquid is equal to the external pressure. It is also the condensation point. The freezing point is the temperature at which liquid and solid coexist in equilibrium. It is also the melting point.
What do the melting point and freezing point have in common?
The freezing point of an item can be equal to the melting point in some cases but not in all.the freezing point and the melting point both have to deal with temp.items with equal melting and freezing points:icemercuryacetic acid
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.
What is freezing point equal to?
Yes, provided the environment is at the same pressure. Changing pressure (for instance, on top of a mountain vs. sea level) will change the freezing/ melting/ boiling points. For example, at 32 degrees Fahrenheit (0 degrees celcius), both liquid water and ice can exist, so it is the melting point of one and the freezing point of the other. Hope that clears things up.

What is meant by freezing temperature of platinum?
The freezing point of water is 32 degrees Fahrenheit. This is equal to 0 degrees Celsius. The freezing point of platinum is 3,214.9 degrees Fahrenheit, which is equal to 1,768.3 degrees Celsius.
What temperature is gold at freezing point?
The boiling point of gold is 2807°C. The freezing point of gold is 1064.18°C.
When a substance freezes what causes the liquid phase to change into the solid phase?
When a liquid is cooled, the average energy of the molecules decreases. At some point, the amount of heat removed is great enough that the attractive forces between molecules draw the molecules close together, and the liquid freezes to a solid. Microscopic view of a liquid. Microscopic view of a solid. The temperature of a freezing liquid remains constant, even when more heat is removed. The freezing point of a liquid or the melting point of a solid is the temperature at which the solid and liquid phases are in equilibrium. The rate of freezing of the liquid is equal to the rate of melting of the solid and the quantities of solid and liquid remain constant.
When 1 kg of a substance changes from solid to liquid at its melting point it must absorb an amount of heat equal to which of the following?
It must absorb heat equivalent to its specific latent heat (Kilojoules per kilogram).
At what temperature does ice melt in Kelvin?
To convert degrees Celsius to Kelvin, add 273. 15 to the temperature. So zero degrees Celsius is equal to 273. 15 Kelvin, the freezing and melting point of water.
