Freeze-Thaw Weathering
This action can widen the cracks in the rock, and when the temperature rises above freezing, the ice thaws, allowing the water to seep further into the cracks. As this process of freezing and thawing happens repeatedly, the rock begins to weaken and eventually breaks apart into angular fragments.
The correct answer is B,
<span>It is endothermic, with both positive enthalpy and entropy changes.</span>

An adiabatic process is one that involves no heat transfer. Work done is the relationship between work and the change in internal energy in an adiabatic process.
In the case of an adiabatic process heat transfer is zero ( Q = 0 ), so internal energy is equal to the Work done.
According to the 1st law of Thermodynamics;
Q= ΔU + W
In an adiabatic process: Q= 0
So,
ΔU= -W
The first law of thermodynamics with Q=0 shows that all the change in internal energy is in the form of workdone.
When we apply force "F" to a block, the body moves with some acceleration or, moreover, its speed increases or decreases depending on the direction of the force. The system's kinetic energy changes as speed increases or decreases.
Since we are aware that energy cannot be created or destroyed, it must be changed into another form. This perspective refers to it as completed job.
When negative energy is finished, the energy declines, and when positive energy is finished, the energy rises. Now that we understand how to assess work done,
