Why do water droplets form on the outer surface of the container containing cold substance?
Summary
TLDRIn this educational video, Mahita explores the phenomenon of condensation, explaining why water droplets form on the outside of cold containers, windows, and glasses. She clarifies that the presence of water vapor in the air, known as humidity, is key to this process. When humid air comes into contact with a cold surface, the vapor cools and condenses into visible droplets. The video also touches on dew formation and the role of temperature in these natural occurrences, providing a simple yet informative explanation for everyday condensation events.
Takeaways
- 🌡️ The phenomenon of water droplets forming on surfaces is due to condensation.
- 💧 Condensation occurs when humid air comes into contact with a cold surface, causing the water vapor in the air to cool down and turn into liquid water droplets.
- 🌫️ Air contains water vapor, which is referred to as humidity.
- 🔥 Heating water turns it into vapor, known as water vapor, and cooling water vapor turns it back into liquid water.
- 🥤 When cold water is poured into a glass, the water vapor in the surrounding air condenses on the outside of the glass, forming droplets.
- 🌞 Water droplets on a window or mirror in the morning are also a result of condensation, as the air temperature drops during the night, causing water vapor to condense.
- 🌳 The process of water vapor condensing into droplets is also responsible for the formation of dew on grass.
- 🍹 Water droplets forming on the outside of a glass on a hot day is another example of condensation, as the cold drink inside the glass cools the air around it, causing water vapor to condense.
- 📢 The video is part of an educational series aimed at explaining scientific phenomena like condensation.

Q & A
What is the main topic of the video?
-The main topic of the video is condensation and why water droplets form on various surfaces under different conditions.
What causes water droplets to form on the outer surface of a container with a cold substance?
-Water droplets form on the outer surface of a container with a cold substance due to the condensation of water vapor from the air when it comes into contact with the cold surface.
Why do water drops appear on the outside of a window or mirror in the morning?
-In the morning, water drops appear on the outside of windows or mirrors because the temperature drops during the night, causing the water vapor in the air to cool down and condense into water droplets.
What is the reason for water droplets collecting on the outside of a glass on a hot day?
-On a hot day, water droplets collect on the outside of a glass because the cold temperature of the glass causes the surrounding humid air to cool down and the water vapor to condense into droplets.
What is condensation in the context of this video?
-In the context of this video, condensation is the process where water vapor in the air cools down and turns into liquid water droplets when it comes into contact with a cold surface.
What is the relationship between air and water vapor?
-Air contains water vapor, and the amount of water vapor present in the air is known as humidity. When air with water vapor contacts a cold surface, the vapor can condense into water droplets.
How does the process of condensation relate to the formation of dew on grass?
-The process of condensation is the same for the formation of dew on grass. During the cooler night temperatures, the water vapor in the air condenses and forms droplets that collect on the grass, creating dew.
Why is it important to understand the concept of condensation?
-Understanding condensation is important as it helps explain various natural phenomena such as the formation of dew, fog, and the appearance of water droplets on cold surfaces, which are all related to changes in temperature and humidity.
What does the video suggest for viewers who are new to the channel?
-The video suggests that viewers who are new to the channel should subscribe and press the bell icon to receive notifications for more interesting videos on similar topics.
How does the video encourage viewer engagement?
-The video encourages viewer engagement by asking viewers to like, share, comment, and subscribe for more content, indicating that interaction and subscription are appreciated.
What is the role of humidity in the process of condensation as explained in the video?
-Humidity plays a crucial role in the process of condensation. The higher the humidity, the more water vapor is present in the air, which increases the likelihood of condensation when the air comes into contact with a cold surface.

hello everybody this is mahita welcome
to smart education in your hands
have you ever think why does water
droplets form on the
outer surface of the container
containing cold substance
or have you think why do water drops
form on the
outside of a window mirror in the
morning or else
have you think why do water droplets
collect on the
outside of a glass on a hot day do you
want to know the answer for all these
questions
then you have to watch this video
completely
before revealing the answer if you are
new to my channel
then please subscribe to my channel and
don't forget to press the bell icon for
more interesting videos like this okay
let's move on to the answer
the answer for all these questions is
only one
that is due to condensation condensation
what is condensation condensation means
the water which collects as droplets on
a cold surface
when the humid air is in contact with it
do you know
air is having water vapor the amount of
water vapor
present in the air is known as humidity
of the air
and you have to remember another fact
that
when we heat the water it converted into
vapor
this vapor is known as water vapor
similarly
if we cool down this water vapor then it
again
converted into water then how is the
droplets on a glass related to this
water vapor
yes they are related i will explain you
for example
if you pour some cold water on a glass
remember air is having water vapor right
when the air which is having water vapor
strikes this glass
then the water vapor present in the air
is cool downs
to cut it then it converted into water
so
this is the reason for the existence of
water droplets outside a glass
when we pour some cold water into the
glass
okay then why do water drops form on the
outside of window mirror
in the morning yes this is also due to
condensation
because during the night time the
temperature cooldowns
the water vapor present in the air also
cool down
so it converted into water this is the
reason for the existence of water
droplets
on the window mirror in the morning and
the similar process is
there when we observe the water droplets
and the grass too
this is also known as dew and this
is the reason the condensation is the
reason for the collection of
water droplets outside the glass on a
hot day
