If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
Which term is defined as the process by which a substance changes state from solid to liquid-?
melting
What does a melting point of a substance indicate?
It indicates that the substance has turned to a liquid.
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
Can the melting point of a substance change over time?
does the melting point of a substance change over time
The temperature at which a substance changes from a liquid to a solid is the?
This is called the melting point, and the temperature is different for every material. For pure water, it is zero degrees Celsius, or 32 degrees Fahrenheit. Determining the melting point of any material is an important clue to determining what the material is.
In the experiment of determining melting point why each time fresh paraffin liquid should be taken?
Paraffin oil is nontoxic, noncorrosive and stable.
What is the purpose of determining boiling point and melting point?
Boiling point- the temperature and pressure at which a liquid and a gas are in equilibrium. But also, it is very useful in determining the purity of a substance. If the melting point is known of the pure substance, than you can measure the melting point of what you've got and see if it matches. If the melting (or boiling) point is the same, than that is a good indication that the compound you have is what you think it is, and it is pure. If they are different from each other, that indicates that your compound is not pure.
If a sample contained 1 gram of pure substance A and another test tube contained 4 grams of pure substance A how would the melting point differ and how would the experiment differ?
The melting point is independent of the quantity. What changes is the amount of heat which must be supplied.
When a substance is melting the temperature of the substance what?
it decreases.
Which term is defined as the process by which a substance changes state from solid to liquid-?
melting
When an obtained melting point range is broad what does it tell about the substance?
strong intermolecular forces attract the molecules
What does a melting point of a substance indicate?

How does boiling point and melting point find a substance?
what is the melting point and boiling point of substance
How many degrees is the melting point?
The melting point of a substance varies according to the properties of that substance
Can the melting point of a substance change over time?
