Experiment for pure and impure naphthalene?
It is easily checked by melting point of Naphthalene, if it is pure its melting point is 79 Celsius otherwise less than 79 Celsius.
In the experiment of determining the melting point of a substance why the substance is stirred constantly?
The purpose is the homogenization of the sample temperature.
What is the melting point and boiling point of gallium?
The melting point is 302.9146 K (29.7646°C, 85.5763°F) The boiling point is 2477 k (2204 °c, 3999 °f) Edit: The boiling temperature for gallium is quoted elsewhere as 2403°c. See discussion section.
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.
The temperature at which a solid melts is called?
melting point
What does the flat portion of the temperature time graph in the experiment of melting point indicates?
The melting point was attained.
What does a solid compound not have?
A melting point under the temperature of the experiment.
Experiment on the melting and freezing point of stearic acid?
90 degrees Celsius
Why does an increase in pressure lead to lower melting point for water?
See this link for a detailed discussion.
How do you prove that glucose do not raise the melting point of stearic acid?
No, impurities do not raise the melting point of Stearic Acid, they decrease it. All impurities decrease the melting point of solids.
Experiment for pure and impure naphthalene?
It is easily checked by melting point of Naphthalene, if it is pure its melting point is 79 Celsius otherwise less than 79 Celsius.
In the experiment of determining the melting point of a substance why the substance is stirred constantly?
The purpose is the homogenization of the sample temperature.
What do you call the temperature at which a solid changes to a liquid?
This is the melting point.
What has a lower melting point ice or ice cream What experiment can you use to prove this?
it's -0000 degreee calcius
What is the melting point and boiling point of gallium?
The melting point is 302.9146 K (29.7646°C, 85.5763°F) The boiling point is 2477 k (2204 °c, 3999 °f) Edit: The boiling temperature for gallium is quoted elsewhere as 2403°c. See discussion section.
Which term is defined as the temperature at which a substance changes from a solid to a liquid state?
melting point
Can ice melt faster in hot water than a marshmallow?
yes ice can melt faster because it has 0 degree melting point as compare to marsh mallow has greater melting point True to a point, but the difference in latent heat of fusion may affect the relative speed of melting. You''ll have to experiment!
