Why do you see droplets on leaves?
Mostly they would be water droplets which may be because of rainfall, morning dew (condensation) or irrigation.
Can you sit on clouds?
No, clouds are made up of tiny water droplets or ice crystals and are not solid enough to support the weight of a person. Attempting to sit on a cloud would not be possible as you would pass right through it.
A cloud on the earths surface?
A cloud on Earth's surface is a fog. Fog occurs when the air near the ground cools to its dew point, causing water vapor to condense into tiny water droplets. This reduces visibility and can affect travel and daily activities.
Can you sleep on clouds?
No, clouds are made up of tiny water droplets or ice crystals which cannot support the weight of a human or any object. Clouds are also very high up in the sky, so it would be impossible to physically sleep on them.
Who invented water thermometers in 1593?
The first water thermometer was created during the 16th century. In the year 1593, Galileo Galilei did the existing thermoscope one step better and created a basic water thermometer. This newer version was the first type of thermometer to allow variations in temperature. Galileo found that, if he used liquid that was less dense than water, he could suspend those liquids in a vial of water, which would rise as the temperature increased. Galileo was able to take the information he discovered and develop a model of a thermoscope that used fine droplets of alcohol. These droplets maintained their cohesion in the water and would rise to the top as the temperature of the water slowly increased. There are those that believe the use of alcohol by Galileo later inspired the use of mercury.
