Introduction:
As you know that, there are so many chemical compounds present on our earth. Many of
them makes solid metals. Do you know that? There are some metals can melt on
the palm of our hand.
Most of the people knows that, Gallium is one of the metal which
can melt on the palm of our hand. But, Gallium is not the only metal which can
melt on palm of our hand.
There are two more metals. In this blog we will discuss “Unknown
fact Metals can melt on palm of our hand”.
What is palm of hands?
The anterior part of the hand present in the central region is
called as palm.
What is temperature?
Temperature is the physical quantity which is used to expressing
hot and cold.
Note: Normal Temperature of human body is 38° C
What is melting point?
Melting point of any substance is the temperature at which solid
changes into the liquid.
What is degree Celsius?
It is a scale known as “Centigrade Scale” used to measure the
temperature by International System.
Unknown fact Metals can melt on palm of our hands
There are total Three Metals which can melt on the palm of our
hand: Gallium, Cesium, Francium.
1] Gallium
Appearance
(Color) of Gallium is like “Silver blue”.
Its atomic
number is “31”.
Symbolically
it is represented by “Ga”.
Melting
point of gallium in degree Celsius is 29.77º C.
Melting
point of gallium in Fahrenheit is 85.59º F.
Reason:
why gallium melts on the palm of our hand?
As you
know that, the temperature of a human body is 38° C and to melt a Gallium metal
there is required 29.77º
C. That means, temperature of our body is more than the temperature required to
melt the Gallium. This is a reason Gallium melts on the palm of our hand.
2] Cesium
Appearance
(Color) of Cesium is like “Pale Gold”.
Its atomic
number is “55”.
Symbolically
it is represented by “Cs”.
Melting
point of Cesium in degree Celsius is 28.4º C.
Melting
point of Cesium in Fahrenheit is 83.12º F.
Reason:
why Cesium melts on the palm of our hand?
As you
know that, the temperature of a human body is 38° C and to melt a Cesium metal
there is required 28.4º
C. That means, temperature of our body is more than the temperature required to
melt the Cesium. This is a reason Cesium melts on the palm of our hand.
3] Francium
Appearance
(Color) of Francium is like “Metallic”.
Its atomic
number is “87”.
Symbolically
it is represented by “Fr”.
Melting
point of Francium in degree Celsius is 27.00º C.
Melting
point of Francium in Fahrenheit is 80.60º F.
Reason:
why Francium melts on the palm of our hand?
As you
know that, the temperature of a human body is 38° C and to melt a Francium metal
there is required 28.4º
C. That means, temperature of our body is more than the temperature required to
melt the Francium. This is a reason Francium melts on the palm of our hand.
Note: Do not try at home to melt any of the above metal in your hand.
I hope that, you have understood about “Unknown fact Metals can melt on palm
of our hands”.
