Put a cup of water in a windowsill for a few days. Everyday mark with a marker how much the water level has gone down. When it goes down, that means the water has evaporated.
What else can I help you with?
How could you set up experiment to show evidence of evaporation?
Leave water in a dish in the sun, place a clear plastic sheet several centimeters over the dish in a tent-like shape, and have another dish on both sides of the primary dish. The water from the primary will end up in the collection dishes because the water will evaporate and then be stopped on the sheet, and drip in to them.
What is the difference between positive and negative control in an experiment?
In an experiment, a positive control is used to show that the experiment can detect a specific response, while a negative control is used to show that the experiment does not detect a response when it should not.
Is evaporation a controlled variable?
Evaporation is not a controlled variable, as it is a natural phenomenon affected by various factors such as temperature, humidity, surface area, and air movement. In an experiment, researchers may try to control factors that influence evaporation to study its effects on other variables.
Why is a cover the beaker in TLC experiment?
Covering the beaker during a TLC experiment helps to prevent evaporation of the solvent, which could lead to changes in the concentration of the compounds being analyzed. Additionally, it helps to maintain a stable environment inside the beaker, ensuring consistent results during the experiment.
What is a sequence of precisely stated steps that describe how an experiment is done using the appropriate materials called?
A sequence of precisely stated steps that describe how an experiment is done using the appropriate materials is called a protocol. It outlines the procedures, materials, and techniques required to conduct the experiment in a reproducible manner. Following a protocol ensures consistency and accuracy in scientific research.
What rate of evaporation was observed in this experiment?
The rate of evaporation observed in the experiment was 0.5 mL per hour.
What is the best measurement in an evaporation experiment?
ammount of water evaporated.
Describe the oldest method of obtaining salt from seawater?
evaporation
What kind of experiment would explain separation of salt water solution?
evaporation or boiling!!!
Can you show me a experiment?
What did Dalton's experiments show

How could you design an experiment to show how a fault is formed?

What all does it take to complete a science experiment essay?
If you wish to write an essay about a science experiment, you should describe the purpose of the experiment, and the way in which the experiment was performed, and the results of the experiment, and the conclusions that are drawn from those results. If you want to be fancy, you might also describe what further experiments may be needed to continue to explore the subject of the first experiment.
What did Dalton's experiment show?
He showed that you can show the true show when you show it correctly.
