Entropy

In physics, entropy means the amount of disorder or the degree of randomness associated with a thermodynamic system. The system is not self-organized when the entropy of the system is high. For instance, when a system is at an elevated temperature, its molecules are in random motion, vibrating and colliding with each other. During this scenario, the probability of finding a molecule at a particular place twice, is low. Under this circumstance, the system can be said to be in a high entropy.

Question

Pl:1: this was all information that was given to me. If need j would need to look it up online.

Experiment 1: The atmosphere
a) Calculate the mass of air in a typical classroom (50 feet
long, 30 feet wide, 10 feet high) at a temperature of 20 C.
b) Calculate the total mass of Earth's atmosphere, considering
that the air pressure is 14.7 pounds per square inch.
c) Going back to the classroom, let's assume that the relative
humidity if the classroom at 20 C is 50%. What is the
partial pressure of the water vapor in the air? (See the final
problem in HW CH 18). How much water is suspended in
the air in the classroom (in liters)
d) Extrapolating that to the entire Earth (use your answer to a
and b), how much water is there in Earth's atmosphere?

The Weather Monitor. Your South American expedition splits into two groups: one that stays at home base, and yours that goes off to set up a sensor that will monitor precipitation, temperature, and sunlight through the upcoming winter. The sensor must link up to a central communications system at base camp that simultaneously uploads the data from numerous sensors to a satellite. In order to set up and calibrate the sensor, you will have to communicate with base camp to give them specific location information. Unfortunately, the group's communication and navigation equipment has dwindled to walkie-talkies and a compass due to a river-raft mishap, which means your group must not exceed the range of the walkie-talkies (3.0 miles). However, you do have a laser rangefinder to help you measure distances as you navigate with the compass. After a few hours of hiking, you find the perfect plateau on which to mount the sensor. You have carefully mapped your path from base camp around lakes and…

⦁ “God himself could not sink this ship” This is an advertisement for the Titanic, produced in the early 1900s. However, after colliding with an iceberg at dawn on April 15, 1912, two rivers were formed, and out of the 2,200 people on board, 1,500 people, including the captain, sank with the ship. According to a later investigation, the “temperature change theory” (DBTT theory) was the most promising cause of the sinking. Give a brief guess of the cause of the ship's sinking in relation to temperature.
