name all the factors that speed up the rate of evaporation
Temperature is higher Density is lower Surface area is larger Airflow over the liquid is greater
1 of 10
name all the factors that speed up the rate of condensation
Temperature of the gas is lower. Airflow is less Density is higher Temperature of the surface the gas touches is lower
2 of 10
Explain why the rate of evaporation increases when temperature is higher
- At higher temperatures, the average particle energy will be higher, so more particles will have enough energy to escape
3 of 10
Explain why the rate of evaporation increases when density is lower
- The forces between the particles will usually be weaker, so more particles will have enough energy to overcome these forces and escape the liquid.
4 of 10
Explain why the rate of evaporation increases when surface area is larger
- More particles will be near enough to the surface to escape the liquid.
5 of 10
Explain why the rate of evaporation increases when Airflow over the liquid is greater
- The lower the concentration of an evaporating substance in the air its evaporationg into, the higher the rate of evaporation. - A greater airflow means air above the liquid is replaced more quickly, so the concentration in the air will be lower.
6 of 10
Explain why the rate of condensation will be higher if Temperature of the gas is lower.
The average particle energy in the gas is lower. So more particles will slow down enough to clump together and form liquid droplets.
7 of 10
Explain why the rate of condensation will be higher if Airflow is less
The concentration of the substance in the air will eb higher, and so the rate of condensation will be greater.
8 of 10
Explain why the rate of condensation will be higher if Temperature of the surface the gas touches is lower
Because they lose energy? it didnt have it in the book.
9 of 10
Explain why the rate of condensation will be higher if Density is higher
The forces between the particles will be stronger. Fewer particles will have enough energy to overcome these forces and will instead clump together and form a liquid
