A Mineral is any occurring, inorganic, crystalline substance ( normally an element or a compound) that possesses a fairly definite chemical composition and a distinctive set of physical properties. They are formed naturally in the Earth, they are usually solid, inorganic, have a crystal structure, and form naturally by geological processes.
Argon monatomic in nature because it is a noble gas and has completely filled shells and thus does not form a bond with other elements.
The heat that creates this temperature change coming from change in the internal energy of the system as per as first law of thermodynamics.
<h3>What is Boyle's law ?</h3>
A law stating that the pressure of a given mass of an ideal gas is inversely proportional to its volume at a constant temperature.
As we know, Boyle's law only works when the gas is kept at a constant temperature
Here,
When volume of gases decreased, it means work done has occurred on the system, so the work done is used for raising internal energy of the gas and the other is released as the thermal energy.
So,
According to 1st law of thermodynamics,
we know Q = ΔU + W i.e, change in internal energy and work done. So this is a reason. Changing temperature occurs.
