Answer:
3. One example of condensation is dew forming on grass or leaves early in the morning when the air is cooled/cooling.
4. This is called freezing. For example, when water turns into ice (a solid) because it freezes.
5. This is called melting. The butter reached its melting point and turned into a liquid.
6. Adding or removing energy causes changes in states of matter. Temperature for example can cause melting and freezing.
7. Water which collects as droplets on a cold surface when humid air is in contact with it.
8. Evaporation/vaporization
9. before- particles are compact
during- particles vibrate
after- the particles move freely
10. condensation because it is going from gas into a liquid
11. Evaporation, I know because when liquid gets heated after a period of time and it reaches its boiling point, it will begin evaporating.
12. When a solid is heated the particles gain energy and start to vibrate faster and faster. ... Although the particles are still loosely connected they are able to move around. At this point the solid is melting to form a liquid. The particles in the liquid are the same as in the solid but they have more energy.
13. Sublimation is the process of transformation directly from the solid phase to the gaseous phase, without passing through an intermediate liquid phase.
14. freezing because particles are becoming compact and getting slower because of decrease in temperature
15. Examples are mothballs, dry ice, snow in the winter months, freeze-drying (ice crystals in a frozen food bag), air fresheners, and printers that print out high-resolution images.
16. Try and think of it in terms of the molecules. The temperature is such that the molecules are all bound together into a solid. Occasionally a surface molecule picks up enough energy to break it bond,.. a statistical probability ,and drifts away. The overall temperature of the solid is reduced by that event,as temperature is just an average of the energy. A little more heat flows into the material ,from the ambient environment, and another molecule escapes, and so the process continues….. if the concentration of the molecules in the vapour space above the solid, is low the reverse process of molecules condensing onto the surface,and releasing energy back into the solid is low.
