This project explores the relationship between temperature and evaporation rate. By conducting experiments at varying temperatures, students gain valuable insights into physical chemistry.
If the temperature of water is increased, then the evaporation rate will also increase due to higher kinetic energy.

Measure an equal volume of water in each beaker.
Set one beaker at room temperature, one on low heat, and one in ice water.
Stir each beaker gently to ensure even temperature.
Use the thermometer to monitor the temperature of each beaker.
Record the initial weight of the water in each beaker.
Every hour, measure and record the weight of water left in each beaker.
Continue for several hours until significant evaporation is observed.
Analyze the data to determine the relationship between temperature and evaporation rate.
You should observe that the beaker with the highest temperature has the least amount of water left, demonstrating that higher temperatures increase evaporation rates.

Volume of water, Type of container, Time duration for observation
Be careful when handling hot water and heat sources. Use gloves if necessary.
Create graphs to visually represent your findings.
Explain the science behind evaporation and temperature.
Engage the audience with questions about their experiences with evaporation.
Discuss practical applications of evaporation in nature.
Calibrate your thermometer and take multiple readings if needed.
Humidity, air movement, and surface area can all impact evaporation rates.
Yes, you can conduct experiments to observe condensation as well!
