The boiling point is the temperature at which a substance changes from a liquid to a gas, while the melting point is the temperature at which a substance changes from a solid to a liquid. These points are specific to each substance and can be used to identify and characterize different materials. The boiling point and melting point are important properties in chemistry and are often used to determine the purity and composition of a substance. **

Boiling point is the temperature at which a substance changes from a liquid to a gas. At the boiling point, the vapor pressure of the liquid is equal to the atmospheric pressure, allowing the liquid to vaporize and form bubbles of gas. Different substances have different boiling points, which can be influenced by factors such as atmospheric pressure and the composition of the substance. **

The boiling point of a molecule is determined by the strength of the intermolecular forces between its molecules. Bromine (Br2) has a higher boiling point than chlorine (Cl2) because bromine molecules are larger and have more electrons, leading to stronger London dispersion forces between the molecules. These stronger intermolecular forces require more energy to overcome, resulting in a higher boiling point for bromine compared to chlorine. **

Yes, the boiling temperature and boiling point are the same thing. The boiling point is the specific temperature at which a substance changes from a liquid to a gas, while the boiling temperature refers to the temperature at which this phase change occurs. So, in essence, they both refer to the same temperature at which boiling occurs. **

The flash point and boiling point of a substance are located on its phase diagram. The flash point is the temperature at which a substance gives off enough vapor to ignite in air, while the boiling point is the temperature at which a substance changes from a liquid to a gas. These points are important in determining the safety and handling of a substance, as they indicate the temperature at which it can undergo significant changes in its physical state. **

Carbon does not have a boiling point in the traditional sense because it sublimes directly from a solid to a gas at a temperature of around 3915 degrees Celsius. This process is known as sublimation, where a substance transitions from a solid to a gas without passing through the liquid phase. **

The boiling point of a substance is determined by its intermolecular forces. Generally, the higher the intermolecular forces, the higher the boiling point. Among the given options, the boiling point of water (100°C) is the highest. This is because water molecules are held together by strong hydrogen bonds, which require a lot of energy to break and therefore result in a higher boiling point compared to the other substances. **

The boiling point of a substance increases when the external pressure increases. This is because a higher pressure makes it more difficult for the molecules of the substance to escape into the gas phase, requiring them to reach a higher energy level before they can boil. As a result, the boiling point increases as the pressure increases. Conversely, a decrease in pressure will lower the boiling point of a substance. **
