Are substances with weak intermolecular interactions likely to be liquids at higher or lower temperatures?
Substances with weak intermolecular interactions are likely to be liquids at lower temperatures. This is because weak forces, such as van der Waals or dispersion forces, require less energy to overcome, allowing the molecules to remain in a liquid state at lower thermal energies. As temperature increases, these substances are more likely to transition to a gaseous state as the kinetic energy overcomes the weak intermolecular forces.
What else can I help you with?
Do polar substances dissolve in non-polar liquids?
No, polar substances do not dissolve well in non-polar liquids because they have different intermolecular forces. Polar substances are attracted to other polar substances due to their opposite charges, while non-polar substances are attracted to each other due to London dispersion forces.
Most substances are?
Most substances are either solids, liquids, or gases at room temperature, depending on their molecular structure and intermolecular forces. The state of a substance can change with temperature and pressure.
What are the dissolving properties of the 3 liquids?
To assess the dissolving properties of three liquids, we typically consider their polarity, solubility, and interactions with solutes. Polar liquids, like water, effectively dissolve ionic and polar substances due to strong dipole interactions. Nonpolar liquids, such as hexane, dissolve nonpolar substances but struggle with ionic or polar compounds. Lastly, polar protic solvents (e.g., ethanol) can dissolve a range of substances due to both hydrogen bonding and dipole interactions, making them versatile solvents in various applications.
Why do some liquids mix and some do not?
Liquids mix when the intermolecular forces between molecules of different liquids are similar and can overcome any repulsive forces. Liquids that do not mix typically have different intermolecular forces, leading to limited interactions between molecules and preventing a homogeneous mixture.
Why can't liquids change volume but gasses can?
The intermolecular strength is higher in liquids than in gases.
Why are liquids and gas's not stable?
because of intermolecular interactions and also possible of polarizing effect
Are intermolecular forces are responsible for the function of DNA- the taste sensations- the existence of liquids and solids- the shape of protein molecules- or all of the above?
Intermolecular forces are responsible for the function of DNA, the taste sensations, the existence of liquids and solids, and the shape of protein molecules. These forces play a crucial role in the structure, stability, and interactions of molecules in biological systems and in the physical properties of substances in different states of matter.
Do polar substances dissolve in non-polar liquids?

Can you please-Compare the melting points of substances that are gases at room temperature with solids and liquids?
Substances that are gases at room temperature typically have lower melting points than solids and liquids because their intermolecular forces are weaker. Gases have molecules that are further apart, making it easier to overcome these weak forces to change their state. Solids and liquids have stronger intermolecular forces that require more energy to break, resulting in higher melting points.
Which intermolecular force is present is present in solids and liquids that are composed of non polar molecules?
London dispersion forces (instananeous dipole - induced dipole interactions)
Do polar or non polar liquids have a greater capillary action?
Polar liquids have a greater capillary action than nonpolar liquids because polar liquids have molecules that exhibit stronger intermolecular forces, such as hydrogen bonding, which allow them to "climb" up a surface more easily. Nonpolar liquids have weaker intermolecular forces, reducing their capillary action.
Why are some substances gases and others liquids at room temperature?
At room temperature, substances can exist in different states (solid, liquid, gas) based on the strength of intermolecular forces between their molecules. Gases have weak intermolecular forces and high kinetic energy, allowing them to move freely. Liquids have stronger intermolecular forces but still enough kinetic energy to flow. The state of a substance at room temperature depends on the balance between these forces and kinetic energy.
What kind of forces act between molecule?
Intermolecular forces
Why can't liquids change volume but gasses can?
The intermolecular strength is higher in liquids than in gases.
