Cloud Bottle Manufacturer,Supplier and Exporter in India

Product Code : EL-P-10755

Quick Answer: The Cloud Bottle is an apparatus for making a cloud in a bottle: a few drops of water are added, air is pumped in, and a quick-release top is opened so that rapid decompression forms a cloud. A liquid crystal thermometer strip shows the temperature changes, and the bottle is approximately 26 cm tall.

About This Product

Cloud bottle experiments show how clouds form when air cools. Compressing the air in the bottle warms it, and when the pressure is released quickly the air expands and cools, so water vapour condenses and a cloud appears. Students add a few drops of water, pump in air, release the top and watch the thermometer strip to link pressure, temperature and condensation. The activity suits lessons on the behaviour of gases and on the water cycle and weather.

Frequently Asked Questions

Q1. How is a cloud made with the Cloud Bottle?
Remove the top, add a few drops of water, pump air into the bottle, then use the quick-release top. Rapid decompression forms a cloud inside the bottle.

Q2. How are temperature changes measured?
A liquid crystal thermometer strip measures the temperature changes throughout the experiment.

Q3. What does it teach?
It shows the relationship between pressure and temperature in a closed container.
