Err... water has no melting point. Ice melts, and water evaporates or freezes
To determine the melting point of a compound, one can use a melting point apparatus. The compound is heated gradually until it changes from a solid to a liquid state. The temperature at which this change occurs is recorded as the melting point of the compound.
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
The melting and boiling points of a substance are characteristic physical properties that can be used to assess purity. A pure substance will have a sharp melting or boiling point, occurring at a specific temperature range. Impurities tend to disrupt the orderly arrangement of particles in the substance, leading to a broader or lower melting/boiling point compared to the pure form. By comparing the experimental melting or boiling point of a sample to the literature values for the pure substance, one can determine the level of purity.
The observed melting point of copper (II) oxalate may not meet the theoretical value due to impurities in the sample or incomplete reaction during preparation. Factors such as water content, incomplete conversion of starting materials, or presence of unreacted starting materials can influence the melting point. It is essential to ensure purity of reagents, control reaction conditions, and thoroughly dry the product to accurately determine the melting point.
Identifying a compound based solely on its melting point is misleading because different compounds can have the same melting point. Additional tests, such as spectroscopic analysis or chromatography, are required to accurately determine the compound's identity. A single melting point determination is not sufficient as it could lead to a wrong conclusion about the compound present.

One simple test to determine if a solid is pure is to measure its melting point. A pure substance will have a sharp melting point, while impurities will cause the melting point to be lower and more spread out. Comparing the measured melting point to the known melting point of the pure substance can help determine its purity.
If the melting point is under 20 oC the substance is a liquid.
I have gone to 8 websites and it is UNKNOWN ----- It is impossible to determine the melting point of hassium with only some atoms !
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
Knowing the melting point of a substance provides information to determine what the substance is if its unknown. If you are making a substance, checking the melting point will let you know if you have made what you set out to make, (because impurities can mess up the melting point)
Minerals with higher melting points will increase the overall melting point of a rock. Conversely, minerals with lower melting points will decrease the overall melting point. The composition and proportion of minerals in a rock will determine its melting point.
Name this crystalline solid; each compound and material have a different melting point.
To determine the melting point on a phase diagram, locate the point where the solid and liquid phases intersect. This intersection represents the temperature and pressure at which the substance transitions from solid to liquid.
The melting point is an indication of purity.
If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
