WHY DOES SALT MAKE ICE COLDER? LEARN THIS AMAZING PHENOMINA WITH THE HELP OF A SIMPLE EXPERIMENT.
Summary
TLDRIn this educational video, the host explores whether adding salt to ice lowers its temperature. Through a simple experiment, two glasses of ice are compared: one with salt and one without. Initially, both glasses register 0.1Β°C. After adding salt and stirring, the temperature of the salted ice drops significantly to -12Β°C. The science behind this phenomenon is explained: salt disrupts the freezing process by interfering with water's ability to form a crystalline structure, thus requiring a colder temperature for freezing. The video concludes with a reminder to like and subscribe for more science experiments.

Q & A
What is the main focus of the video?
-The main focus of the video is to determine whether adding salt to ice lowers its temperature.
How does the experiment begin?
-The experiment begins with two identical glasses containing ice cubes, ensuring both have the same amount of ice.
What is the initial temperature of the glasses of ice?
-The initial temperature of both glasses of ice is 0.1 degrees Celsius.
What is added to one of the glasses to conduct the experiment?
-Salt is added to one of the glasses to observe its effect on the temperature of the ice.
What is the scientific explanation behind the addition of salt to ice?
-When salt is added to ice, it lowers the freezing point of water, making it more difficult for water to freeze and causing the ice to remain in a liquid state at a lower temperature.
How long after adding salt is the temperature of the ice checked?
-The temperature of the ice with salt is checked after more than five minutes.
What is the observed change in temperature after adding salt?
-After adding salt, the temperature of the ice decreases drastically to minus 12 degrees Celsius.
How does salt affect the freezing process of water?
-When salt dissolves in water, it dissociates into ions that interfere with the formation of a crystalline structure required for freezing, thus lowering the temperature needed for water to freeze.
What happens when salt dissolves in water?
-When salt dissolves in water, it dissociates into its ionic form, such as Na+ and Cl- ions, which disrupt the organization of water molecules into a crystalline structure.
What is the role of salt ions in the freezing process?
-Salt ions get in between water molecules, making it more difficult for them to organize into a crystalline structure, thus lowering the freezing point.
Can other types of salts have a more significant effect on the freezing point?
-Yes, some other salts can dissolve into more particles than table salt, which can lower the freezing point even more.
What is the conclusion of the experiment?
-The conclusion of the experiment is that adding salt to ice does indeed lower its temperature, as evidenced by the drastic decrease in temperature in the glass with salt.
Outlines
π§ Experiment: Salt's Effect on Ice Temperature
This video explores whether adding salt to ice lowers its temperature. The experiment involves comparing two glasses of ice, one with salt and one without. Initially, both glasses have ice at 0.1 degrees Celsius. Salt is added to one glass and stirred. The science behind the experiment is explained: salt lowers the freezing point of water, making it harder for water to freeze. After five minutes, the temperature of the glass without salt remains at 0.1 degrees Celsius, while the salted ice's temperature drops significantly to minus 12 degrees Celsius. This occurs because salt ions interfere with the water molecules' ability to form a crystalline structure necessary for freezing, thus requiring a colder temperature to freeze.

hey everyone welcome back to my channel
today's video is all about an
interesting question does adding salt to
ice lower its temperature to find out
we're going to conduct a simple
experiment and compare two glasses of
ice one with salt and one without salt
so let's get started we have two
identical glasses with ice cubes in
front of us make sure both glasses have
the same amount of ice and let's first
measure the temperature of glass without
adding salt
initially the temperature of both the
glasses is 0.1 degrees Celsius
now we're going to add salt to one of
the glasses and give it a good stir
now let's talk about the science behind
this experiment when salt is added to
ice it lowers the freezing point of
water the freezing point of pure water
is 0 degrees Celsius or 32 degrees
Fahrenheit but when salt is added to
water it interferes with the process of
freezing making it more difficult for
water to freeze this means that the ice
will stay in a liquid state at a lower
temperature than it would without salt
it is about more than five minutes since
we added salt to ice okay now let's
check on our glasses of ice now let
first check the temperature of glass
without ice
as you can see the temperature of glass
without salt is still 0.1 degree now
let's check the temperature of ice with
salt
as you can see there is a drastic
decrease in the temperature and it has
decreased up to a minus 12 degrees
Celsius
let's understand the reason behind it
when salt dissolves in water it
dissociates into its ionic form is now
Plus in CL ions these ions get in
between the water molecules which makes
it more difficult for the water
molecules to organize themselves into a
crystalline structure that is required
for freezing since the salt ions
interfere with the freezing process the
temperature required to freeze the water
becomes lower which means that it takes
a colder temperature for the liquid to
turn into ice this is why adding salt to
ice reduces the temperature at which it
freezes table salt dissolves into two
particles but some other salts can
dissolve into more particles and lower
the freezing point even more that's it
for today thank you for watching this
video I hope you enjoyed our little
experiment and learned something new
