Does intermolecular force change from solid to liquid or liquid to gas?
Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.
How do intermolecular forces affect the boiling point of liquid?
the stronger the intermolecular force, the more energy is required to boil the liquid ...
Why can different substances be i different phases st room temperature?
Different substances have varying intermolecular forces that dictate their phase at room temperature. Substances with strong intermolecular forces, like water, tend to be in a solid or liquid phase at room temperature. In contrast, substances with weaker forces, like gases, are typically in a gaseous phase.
What is the correct order of states from least to greatest intermolecular forces of attraction?
The correct order is: gas < liquid < solid. This is because in the gas phase, molecules are far apart and have weak intermolecular forces, in the liquid phase, molecules are closer together with moderate intermolecular forces, and in the solid phase, molecules are tightly packed with strong intermolecular forces.
What type of intermolecular forces exist in gasoline?
The main intermolecular forces present in gasoline are London dispersion forces, which arise from temporary fluctuations in electron distribution in the molecules. These weak forces allow the molecules to attract each other and remain in a liquid state at room temperature.
what are liquids mobile?
Liquids are mobile because the intermolecular forces between their molecules are weak enough to allow the molecules to move around relative to one another. These intermolecular forces are the forces of attraction between the molecules, and they are what hold the molecules together in a liquid. However, the intermolecular forces in liquids are not as strong as the intermolecular forces in solids, so the molecules in a liquid are able to move around more easily. This is why liquids can flow and take the shape of their container. The strength of the intermolecular forces in a liquid depends on the type of liquid. For example, water has strong intermolecular forces because the molecules of water are polar, meaning that they have a positive end and a negative end. This polarity allows the water molecules to form hydrogen bonds with each other, which are very strong intermolecular forces. As a result, water is a very mobile liquid, but it is not as mobile as a gas, such as air. The mobility of a liquid can also be affected by temperature. As the temperature of a liquid increases, the molecules of the liquid move faster and the intermolecular forces become weaker. This is why liquids become more mobile as they heat up. For example, water at room temperature is a liquid, but it becomes a gas when it is heated to 100 degrees Celsius.visit- In conclusion, liquids are mobile because the intermolecular forces between their molecules are weak enough to allow the molecules to move around relative to one another. The strength of the intermolecular forces in a liquid depends on the type of liquid and the temperature of the liquid.
How do intermolecular forces determine a substance's state?
If the intermolecular forces are great enough they can hold the molecules together as a liquid. If they are even stronger they will hold the molecules together as a solid. Water has nearly the same mass as methane and ammonia molecules, but the greater molecular forces between water molecules causes the water to be liquid at room temperature, while ammonia and methane, with weaker intermolecular forces, are gases at room temperature.
The tendency of the molecules of a liquid at a given tepmpature to evaporate as a result of radom molecular motion?
This is known as vapor pressure. It is influenced by factors like temperature, intermolecular forces, and surface area. Higher temperature and weaker intermolecular forces increase the vapor pressure of a liquid.
What characteristics is the boiling point of a liquid related to?
The boiling point of a liquid is related to the strength of intermolecular forces between its molecules. Molecules with stronger intermolecular forces tend to have higher boiling points. Additionally, the size and shape of the molecules can also influence the boiling point of a liquid.
The forces that account for HF being a liquid while H2 and F2 are gases are known as?
intermolecular forces. In the case of HF, hydrogen bonding exists between HF molecules, which results in stronger intermolecular attractions compared to the London dispersion forces present in H2 and F2. These stronger intermolecular forces in HF allow it to exist as a liquid at room temperature.
Does vapour pressure depend upon the nature of a liquid?
Yes, the vapor pressure of a liquid depends on the nature of the liquid. Factors such as temperature, intermolecular forces, and molecular weight influence the vapor pressure of a liquid. Lower intermolecular forces and higher temperatures lead to higher vapor pressure.
What physical property causes milk or water to freeze?
The freezing point of a liquid, such as water or milk, is determined by the intermolecular forces between the molecules in the liquid. As the temperature decreases, these intermolecular forces become stronger, causing the molecules to arrange in a more organized structure, leading to the solidification of the liquid.
Does intermolecular force change from solid to liquid or liquid to gas?
Yes, the intermolecular forces generally change as a substance transitions from solid to liquid to gas. In solid form, molecules are held together by strong intermolecular forces. In liquid form, these forces weaken to allow molecules to move more freely. In gas form, intermolecular forces are weakest as molecules are far apart and move independently.

Why is water liquid at room temp but oxygen is gas at room temp?
Water molecules have stronger intermolecular forces (hydrogen bonding) that keep them together as a liquid at room temperature. Oxygen molecules have weaker intermolecular forces, so they stay as a gas at room temperature.
Why can different substances be i different phases st room temperature?
Different substances have varying intermolecular forces that dictate their phase at room temperature. Substances with strong intermolecular forces, like water, tend to be in a solid or liquid phase at room temperature. In contrast, substances with weaker forces, like gases, are typically in a gaseous phase.
Compounds' physical state at room temperature can be gas liquid or solid.?
At room temperature, compounds can exist in one of three physical states: solid, liquid, or gas. The state depends on factors like molecular structure, intermolecular forces, and temperature. For example, substances with strong intermolecular forces, like ionic compounds, tend to be solids, while those with weaker forces, like gases, exist in a gaseous state. Liquids, on the other hand, have moderate intermolecular forces, allowing them to flow while maintaining a definite volume.
