How are melting and freezing points similar in a chemical?
Melting and freezing points are both physical properties of a substance related to its phase change from solid to liquid (melting) or liquid to solid (freezing) at a specific temperature. These points are the same temperature for a pure substance under constant pressure and can be used to identify and characterize substances.
What is the Hypothesis of the melting and freezing point of naphthalene?
The hypothesis for the melting and freezing point of naphthalene could be that the melting point of naphthalene will be higher than its freezing point due to the typical behavior of most substances where solids melt at higher temperatures than they freeze. The hypothesis may also include factors like the purity of the naphthalene sample affecting its melting and freezing points.
Is 70 degrees Celsius in a melting or freezing point?
A temperature of 70 degrees Celsius is typically well above both the melting and freezing points of most common substances. For water, its melting point is 0 degrees Celsius and its freezing point is 0 degrees Celsius as well.
Do liquids have melting points?
NO!!! However, on change of physical state;- solid to liquid it is 'melting' liquid to solid it is 'freezing' Similarly liquid to gas it is evaporation/boiling gas to liquid it is condensation. Different substances have different temperature for change of physical state. Water being the scientific standard has; - melting/freezing at 0oC boiling/evaporation at 100oC
What is the difference between water's freezing and melting points?
Water's freezing point is the temperature at which liquid water turns into solid ice, which is 0 degrees Celsius. On the other hand, water's melting point is the temperature at which solid ice turns into liquid water, also at 0 degrees Celsius. Both freezing and melting points occur at the same temperature but represent opposite phase changes.
Where are the freezing points and melting points of gold?
1064.18
If a substance forms crystals when it solidifies its melting and freezing points are the same?
Melting and freezing points are identical.
Is oxygen a melting or freezing point?
Your question cannot be answered as written. Melting/ freezing points are at the same temperatures.
Are freezing and melting points characteristic properties?
Yes, freezing and melting points are characteristic properties of a substance. They are specific temperatures at which a substance changes its state from solid to liquid (melting) or from liquid to solid (freezing) under normal atmospheric pressure.
What is the melting point Freezing point?
Freezing and melting points are synonyms: at this temperature a solid become a liquid or a liquid become a solid.

Why water is 0'c is solid but nitrogen is gas?
Different chemicals have different physical properties, such as melting points (freezing points) and boiling points (vaporization points) waters freezing point is 0* C whereas nitrogen's freezing point is much lower.
Is 70 degrees Celsius in a melting or freezing point?
A temperature of 70 degrees Celsius is typically well above both the melting and freezing points of most common substances. For water, its melting point is 0 degrees Celsius and its freezing point is 0 degrees Celsius as well.
What are the freezing melting boiling and evaporation points of water?
The melting/freezing point of water is oC.The boiling point of water is 100 oC at standard pressure.Evaporation occur at any temperature.
Is freezing a characteristic property?
Yes! Freezing (when a substance becomes solid) and melting points (when a substance becomes liquid) are characteristic properties.
What is gold's freezing point?
1063 °C(lit.) Freezing points and melting points generally can be used interchangeably. Scientific data is reported as the melting point or mp. Purity will also effect the freezing point but very useful in determining the purity of a substance.
