For Teachers

Evaporation (Surface Area, Temperature, Humidity, Presence of Wind) for Primary School

 

For a small surface area, the rate of evaporation of water in the container decreases with time

Direct Link
For a middle size surface area, the rate of evaporation of water in the container decreases with time linearly as the surface is constant
https://iwant2study.org/ospsgx/index.php/968
Direct Link
For a large surface area at the beginning, the rate of evaporation of water in the container decreases with time in the blue trail
This implies larger the surface area the shorter the time taken to evaporate

For a low temperature, the rate of evaporation of water in the container decreases with time linearly in the red trail

For a middle temperature, the rate of evaporation of water in the container decreases with time linearly in the green trail

For a high temperature, the rate of evaporation of water in the container decreases with time linearly in the blue trail.
This implies higher the surrounding temperature the shorter the time taken to evaporate

For a low wind condition, the rate of evaporation of water in the container decreases with time linearly in the red trail
https://iwant2study.org/ospsgx/index.php/968
Direct Link

For a medium wind condition, the rate of evaporation of water in the container decreases with time linearly in the green trail
https://iwant2study.org/ospsgx/index.php/968
Direct Link
For a high wind condition, the rate of evaporation of water in the container decreases with time linearly in the blue trail
This implies higher the wind the shorter the time taken to evaporate

For a low humidity condition, the rate of evaporation of water in the container decreases with time linearly in the red trail
https://iwant2study.org/ospsgx/index.php/968
Direct Link
For a medium humidity condition, the rate of evaporation of water in the container decreases with time linearly in the green trail
https://iwant2study.org/ospsgx/index.php/968
Direct Link

For a high humidity condition, the rate of evaporation of water in the container decreases with time linearly in the blue trail
This implies higher the humidity the longer the time taken to evaporate

Experiment 1

Change the temperature to 30 ◦c

Click play to see a graph appears

Click store to save the graph at 30 ◦c

Look at the time taken when the amount of water left in the container is zero.

Record the hours the water takes to evaporate.

Change the temperature to 20 ◦c

Record the hours the water takes to evaporate

Study the 2 graphs to compare the rate of evaporation of water.

Which temperature causes the water to evaporate faster?
