Answer : The correct option is, (2) gas to liquid
Explanation :
Entropy : It is defined as the measurement of randomness or disorderedness in a system.
The order of entropy will be,
As we are moving from solid state to liquid state to gaseous state, the entropy will be increases due to the increase in the disorderedness.
As we are moving from gaseous state to liquid state to solid state, the entropy will be decreases due to the decrease in the disorderedness.
In option 1, 3 and 4, the entropy increases. while in option 2, the entropy decreases.
Hence, the correct option is, (2) gas to liquid
I believe the answer is Limestone
Limestone is one of the vital minerals that is used to make cement. It is a sedimentary rock composed mostly of the calcium carbonate and, according to mineral coalition, it comprises about 15% of the Earth's sedimentary crust.

<h3>~AH1807</h3>
The objects may exchange heat between each other if they are in contact with each other.
The two objects will allow flow of heat between them if they have a difference in temperature from each other.
The heat will flow from higher temperature object to lower temperature object. The will reach a final temperature (common to each other) and then there will be no heat transfer between each other.
