When an object is heated, its dimensions tend to increase, and this phenomenon is known as spatial expansion. Considering that the linear expansion coefficient of a certain material is equal to 0.00025°C⁻¹, determine the variation in length of a 2 m bar when heated to 50°C.a.
0.025 m
b.
0.125 m
c.
0.5 m
d.
0.05 m
e.
2 m

Explain the concept of entropy and how it is related to the second law of thermodynamics. Give an example of a process that increases the entropy of a system and another example of a process that decreases the entropy. Then, calculate the entropy change of a system that undergoes a change from a gaseous to a liquid state at constant temperature.
