What happens to the speed of molecules in water vapor when it condenses to form a liquid?
The molecules slow down.
What happens to the speed of molecules in water vapor when it condenses to form of a liquid?
The molecules slow down.
How do you describe each phase change?
Endothermic phase changes - the substance is gaining energy (being heated) and the molecules are getting more active.- solid to liquid: melting- liquid to gas: vaporization- solid to gas: sublimationExothermic phase changes - the substance is losing energy (cooling) and the molecules are slowing down.- gas to liquid: condensation- liquid to solid: freezing- gas to solid: depositionMemory helper: exo is like exit, and the heat energy exits the substance during an exothermic phase change.
Would you expect larger or smaller molecules to be components of a more viscous liquid?
Larger molecules make a liquid more viscous. Larger molecules occupy more space compared to smaller molecules which makes a liquid thicker.
Does evaporation speed up or slow down molecules?
Evaporation speeds molecules up, thusly meaning they will "spread out" and convert from a liquid to a gas.
What happens when a solid a liquid and gas when it changes its state?
Well solid to liquid the heat speeds up the molecules and same for liquid to gas but from liquid to solid the coolant slows the molecules down
What happens to the molecules when there is a change in state from liquid to solid?
When a liquid changes to the solid state, the molecules slow down so that they only vibrate in place and can no longer flow like a liquid.
What changes would occur at a molecular level if a liquid is placed in cool conditions?
the motion of the molecules would slow down
How liquid is cooled?
By slowing the molecules down
When water changes to solid the molecules what?
Slow down.
How a solid changes into a liquid?
for example ice is melted down into a liquid
What are the correct description of the phase changes?
a phases change is when a substance goes from being a solid to liquid to gas. in solids the molecules have slowed down and are ridged. In liquids, molecules have free form movement and take the shape of their container. In gases, molecules have free form movement and move quickly, they take up all the space in their containers.
What happens to the speed of molecules in water vapor when it condenses to form a liquid?
The molecules slow down.
What happens to the speed of molecules in water vapor when it condenses to form of a liquid?
The molecules slow down.
What happens to a liquid . When it releases energy?
The liquid cools down. Its molecules move more slowly.
When a liquid is cooled the molecules in that liquid?
I assume you mean what happens to the molecules... They slow down due to the loss of kinetic energy when the liquid is cooled. When they are sufficiently cooled as to cause freezing, that's a different story.
