How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
What processes is most affected by pressure freezing or boiling or melting?
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
What can you tell about the structure of a hydrocarbon if it is liquid at room temperature?
A hydrocarbon that is liquid at room temperature typically consists of a chain of carbon atoms bonded together with hydrogen atoms. The length and branching of the carbon chain, as well as any functional groups present in the molecule, can influence its physical state at room temperature. Generally, shorter carbon chains and less branching result in lower melting points, making the hydrocarbon more likely to be a liquid at room temperature.
Why boiling point of noble gases increase down in the group?
The melting and boiling points increase down the group because of thevan der Waals forces. The size of the molecules increases down the group. This increase in size means an increase in the strength of the van der Waals forces.
Calcium melting point and boiling point?
The melting point of Calcium is 839℃ and the boiling point is 1484℃.
Hydrocarbon boiling points increase the number of carbon or decrease?
Boiling points of hydrocarbons generally increase with an increase in the number of carbon atoms. This is because larger hydrocarbons have stronger London dispersion forces due to increased surface area, which requires more energy to overcome during boiling.
How melting and boiling point varied in a period?
Generally melting point and boiling point increase up to group 6 and then decrease.
What is the trend in melting point and boiling points of the elemets in group 1 and 7?
In Group 1 (alkali metals), the melting and boiling points decrease as you move down the group due to the increase in atomic size and metallic bonding. In Group 7 (halogens), the melting and boiling points increase as you move down the group due to the increase in atomic size and London dispersion forces.
What processes is most affected by pressure freezing or boiling or melting?
Boiling and freezing points of a substance are affected by pressure. An increase in pressure raises the boiling point and lowers the freezing point of a substance. Melting point is not significantly affected by pressure.
How does one increase the melting or boiling point of a substance?
Add impurities (salt and others) to the substance.
What is the meaning when something is boiling or melting?
Boiling occurs when a substance changes from a liquid to a gas at its boiling point, while melting happens when a substance changes from a solid to a liquid at its melting point. Both processes involve an increase in temperature that causes the substance's molecules to gain enough energy to overcome intermolecular forces and change states.
To increase Melting and boiling point of Zinc what is to be done?
To increase MP and BP point of Zinc u should add some impurities in it. The addition of impurities always decreases the melting point .

Does melting and boiling cause physical changes?
Melting and boiling are physical changes.
What is hydrogen's melting and boiling point?
Melting: -259.14 C Boiling: -252.87 C
Do elements compounds and mixtures have fix melting and boiling point?
Elements have fixed melting and boiling points, while compounds have varying melting and boiling points depending on their composition. Mixtures do not have fixed melting and boiling points, as they are composed of multiple substances which each have their own individual melting and boiling points.
What are the Boiling and Melting Points of alkaline earth metal?
The boiling points of alkaline earth metals generally increase down the group. For example, the boiling point of beryllium is around 2469°C and the boiling point of barium is around 1860°C. The melting points also generally decrease down the group.
