Condensation P1
Question | Answer |
---|---|
Roughly, what is condensation? | When gas cools and turns in to a liquid |
Explain, in terms of particles, what happens when a gas condenses.(2) | • When gas cools its particles lose energy and their attractive forces pull them together • If the temperature is cool enough and the particles get close enough it becomes a liquid |
When would a gas condense? | If it came in to contact with a cooler surface |
Explain why the rate of condensation might speed up.(4) | • If gas temperature is lower then more particles lose more energy more quickly • Surface gas touches has lower temperature • If density is higher then attractive forces between particles will be higher • Concentration of the substance in air is less |
