Is ice water a homo or heter mixture?
Ice water is a homogeneous mixture because both the ice and water are in the same phase (liquid) and are uniformly mixed at a molecular level.
In what ways do solutions differ from mixtures?
Solutions are a type of mixture where the components are evenly distributed at a molecular level, while mixtures can have uneven distribution of components. Solutions have a single phase, while mixtures can have multiple phases.
What is evaporation on the basis of molecular structure?
Evaporation is the process where molecules at the surface of a liquid gain enough kinetic energy to overcome intermolecular forces and escape into the gas phase. This occurs when the molecules have enough energy to break free from the liquid phase and move into the gas phase.
What does this illustrate about the amount of stuff per cm as a substance changes from a liquid to a gas?
As a substance changes from a liquid to a gas, the amount of stuff per cm decreases significantly because gases are less dense than liquids. This is due to the increase in molecular motion and separation in the gas phase compared to the liquid phase.
Is plaster a homogeneous or heterogeneous mixture?
Plaster is a homogeneous mixture, as it is composed of a single phase where the materials are uniformly distributed at a molecular level.
What is happening to liquid evaporation in terms of bond and energy levels?
Evaporation is a phase change from liquid to gas, therefore it involves increased energy and decreased bonding on the molecular level.
What is the change in molecular movement when water evaporates?
When water evaporates, the molecules gain enough energy to break free from the liquid phase and enter the gas phase. This results in an increase in the overall movement of water molecules as they transition from being closely packed in the liquid to being more spread out in the gas phase.
Is ice water a homo or heter mixture?
Ice water is a homogeneous mixture because both the ice and water are in the same phase (liquid) and are uniformly mixed at a molecular level.
A solid that has a low melting point and does not conduct in either the solid or liquid phase is a n solid?
molecular

How does matter physically change when it changes its phase or state?
Its motion changes speed on the molecular level
A liquid can dissolve a solid to make a solution?
That's correct! In a solution, the solid (solute) is dissolved in the liquid (solvent) to form a homogeneous mixture. This occurs at the molecular level where the solvent molecules surround and disperse the solute particles to create a single phase.
What is evaporation on the basis of molecular structure?
Evaporation is the process where molecules at the surface of a liquid gain enough kinetic energy to overcome intermolecular forces and escape into the gas phase. This occurs when the molecules have enough energy to break free from the liquid phase and move into the gas phase.
Why don't most solids float on their liquid forms?
Typically, the solid phase of a substance is denser than its liquid phase, because higher molecular energy makes the liquid molecules take up more volume for a given mass.An important exception is solid water (ice) which takes on a lattice molecular shape and expands when it freezes, so ice is less dense and floats on liquid water.
How do phase diagrams for water and carbon dioxide differ?
both have a solid, liquid, and gas phase. it's just that to get CO2 in the liquid phase takes a lot of effort and is highly reactive in terms of it quickly evaporates to the preferred state of gaseous CO2.
When the molecules in a body move with increased speed it's possible that the body will change from a A. liquid to a gas. B. gas to a liquid. C. gas to a solid. D. liquid to a solid.?
Only one phase change of the four is possible, that of a liquid to a gas. Increased molecular energy is related to dissociative phase changes : solid to liquid / liquid to gas.
When the molecules in a body move with increased speed it's possible that the body will change from a a gas to a liquid b liquid to a solid c liquid to a gas d gas to a solid?
Only one phase change of the four is possible, that of a liquid to a gas. Increased molecular energy is related to dissociative phase changes : solid to liquid / liquid to gas.
