Which of the following is described by the equation H2O(s) heat H2O(l)?
The equation describes the process of ice (H2O solid) absorbing heat and melting into liquid water (H2O liquid) at its melting point temperature.
Conclusion of determination of melting point?
The melting point is an important physical property that helps identify a substance and assess its purity. By carefully observing the temperature at which a substance changes from solid to liquid state, we can compare it to the known literature values to confirm the substance's identity. A sharp melting point range indicates a pure compound, while a broad or depressed range suggests impurities.
Why is melting point of magnesium less than calcium although melting point decrease down the group?
The melting point of magnesium is lower than calcium because although melting points generally decrease down a group, there can be exceptions due to variations in atomic size, packing efficiency, and bonding forces. In this case, the smaller size and stronger metallic bonding in calcium result in a higher melting point compared to magnesium, despite being further down the group.
Which molecular solids has the highest melting point?
Diamond has the highest melting point among molecular solids due to its strong covalent bonds in a three-dimensional network structure, which require a significant amount of energy to break and melt the solid.
Boiling and melting point of sulfur?

Is freezing chemical or physical property?
I would say that freezing point is a boiling property because there is no scientific evidence to suggest that it is or indeed ever will be a chemical property. Freezing point is a chemical reaction. Therefor this is a debatable question. Different people may have different views. This is mine."Freezing point" is usually termed as "melting point" in scientific circles. Melting point is defined as the temperature at which the solid and liquid phase of a substance coexist at equilibrium under the pressure of their own vapors. Ice and water coexist at equilibrium at temperature of 32 degrees F when only their own vapor pressures are acting upon them. However, the temperature difference at atmospheric pressure is negligible. As you can see, melting point (freezing point) only depends on the physical conditions acting on the substance, therefore, melting point (freezing point) is a physical property. Melting point is effected (lowered) by the addition of other molecules or ions to the substance. This effect is physical because it depends only upon the number of particles (molecules etc) added and no chemical reaction is required.
Which of the following is described by the equation H2O(s) heat H2O(l)?
The equation describes the process of ice (H2O solid) absorbing heat and melting into liquid water (H2O liquid) at its melting point temperature.

What is the melting point of F2?
The melting point of F2 (fluorine gas) is -219.62 degrees Celsius (-363.3 degrees Fahrenheit). It is a very low melting point due to the weak intermolecular forces between its molecules.

How does freezing point get calculated if boiling point of an aqueous solution is given?
You can calculate the freezing point of an aqueous solution using the equation for colligative properties: ΔTf = i * Kf * m, where ΔTf is the freezing point depression, i is the van 't Hoff factor, Kf is the cryoscopic constant of the solvent, and m is the molality of the solution. By rearranging the equation, you can solve for the freezing point.
What temperature is half way between the freeze and boil point?
The temperature halfway between the freezing and boiling points of water is 32°F (0°C). This is the freezing point of water in Fahrenheit and is halfway between 212°F (boiling point) and 0°F (freezing point).

What process by which a solid changes to a liquid is called?
The process by which a solid changes to a liquid is called melting. It occurs when the solid absorbs enough heat energy to overcome the forces holding its particles together in a solid state, allowing them to move more freely and transition into a liquid state.

The melting point of magnesium is lower than calcium because although melting points generally decrease down a group, there can be exceptions due to variations in atomic size, packing efficiency, and bonding forces.
