When you open a tiffin box you observe some droplets on a lid This is due to?
The heat that is liberated from the food due to packed hot pack tiffin which tries to escape from the food in the form of vapour takes the form of water and settles on the top on the lid of the tiffin.
What causes the formation of water droplet?
When warm air hits the cold surface, it reaches its dew point and condenses. This leaves droplets of water on the glass or can. When a pocket of air becomes full of water vapor, clouds form. Those flat bottoms are where vapor begins to condense into water droplets.
Why water droplets are formed on the lid of the rice bowl after cooking give reasons?
Water droplets on the underside of the lid are present due to the condensation of water vapour to water. Steam comes out of the rice and when it comes in contact with the cool lid it condenses to form water droplets.
Why does my food have condensation?
Condensation or moisture inside food storage containers is normal. Water vapor in the air trapped in the container when it is sealed forms condensation. When a container is placed in a refrigerator, it cools from the outside in, making the inside surface of the container the coldest surface where condensation forms.
Why do droplets of water appear on the surface of cool water bottle?
Solution: This is because water vapour present in air collide with the surface of cold water bottle which and condenses into water droplets. These water droplets collect and form a puddle of water around the bottle.
What do the water droplets represent?
When the drops collide with each other they form bigger and bigger drops of water and represent clouds. When the clouds get enough water in them that they can no longer hold it, the water droplets drop down as rain onto the earth.
Why are drops of water formed when a steel plate is held over the boiling water?
Answer Expert Verified. we find droplets of water on underside of plates that is put on hot bowl of soup because when water is hot in soup, it evaporates and when it reaches the plate, it cools, condenses and form droplets of water on it.
What do you think makes the lid move while boiling?
When water is boiled, the heat energy is transferred to the molecules of water, which begin to move more quickly. Instead of air, the bubbles in a boiling pot of water are actually made up of water — it’s just water in its gaseous state!
