What intermolecular force is attributed to the low density of ice compared to water ?
- Can a gas condesed above the pressure and critical temperature?
-what happens to a substance in the triple point?
Homework Answers
When water freezes, water molecules form a crystalline structure maintained by hydrogen bonding. Solid water, or ice, is less dense than liquid water. Ice is less dense than water because the orientation of hydrogen bonds causes molecules to push farther apart, which lowers the density.
Yes, a gas can be condensed above the pressure and critical temperature.
Triple point: The temperature and pressure at which the solid, liquid, and vapour phases of a pure substance can coexist in equilibrium.

London dispersion forces are present in all substances but are the only significant intermolecular forces in nonpolar substances. ) The density of the liquid state of a substance is greater than the density of its gaseous state. The thermal energy in a liquid allows the atoms within molecules to completely overcome the attractions between them so they flow. Most liquids can be converted to a gas by reducing pressure and/or heating. The...

There is a compound Z that exists in the liquid phase at room temperature and pressure with a vapor pressure of 0.2 atm. When 250 ml of Z is mixed with 250 ml of water the resulting mixture has a lower vapor pressure than predicted. Explain what this means in terms of the intermolecular forces of the solute(Z) and the solvent ( water). Is Z likely to participate in hydrogen bonding? Why or why not. When pure compound Z (as...

Think about intermolecular forces and the stronger the intermolecular force the more energy needed to separate the molecules. Just thinking about this, put the properties below in the correct category. Hints: Vapor pressure is high if it is easy for molecules to escape from a liquid into the gas phase. High surface tension means the liquid molecules do not separate easily Viscosity is the "thickness" of a liquid substance Strong intermolecular forces Weak intermolecular forces Answer Bank high boiling point...

PART 1 Diethyl ether has a particularly low surface tension. This is due to the dominant intermolecular forces between diethyl ether molecules being: Question options: Dipole-dipole interactions Hydrogen bonding. Dispersion forces Metallic bonding PART 2 A solid sample is at a higher pressure and lower temperature then the triple point. What happens when the sample is heated at constant pressure? Question options: Either the solid melts or the solid remains solid can happen, depending upon how much the solid is...
