I think it is called a loess. Please correct me if I am wrong.
He ≤ Ne ≤ Ar ≤ Kr
Ne ≤ He ≤ Ar ≤ Kr
Kr ≤ Ar ≤ Ne ≤ He
Answer:
The correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr
Explanation:
Entropy is the measure of degree of disorderliness or randomness of a substance. Entropy increases with increasing number of electron present in an atom due to increased repulsive force of the electrons. Therefore, the standard entropy of a substance increases with an increase in their atomic masses.
For the given noble gases in this question, Helium (He) has the least atomic mass while Krypton (Kr) has the highest atomic mass.
Thus, the correct order of increasing standard molar entropy for the noble gases is He ≤ Ne ≤ Ar ≤ Kr
b. False
A. true.
The statement that Eisenhower, Kennedy, and Johnson all approved of the United States backing the South Vietnamese in their civil war is absolutely true. After the communist North Vietnam got her Independence in 1954, there began a civil war in South Vietnam. The communist insurgents backed by North Vietnam turned against the South Vietnam government. So US supplied its soldiers in South Vietnam to suppress the communist insurgents and the move was approved by Eisenhower, Kennedy, and Johnson.
Answer:
The sun is what makes the water cycle work. ... Heat causes liquid and frozen water to evaporate into water vapor gas, which rises high in the sky to form clouds... clouds that move over the globe and drop rain and snow. This process is a large part of the water cycle.

Lab Objectives
In this lab you will:
• help the aliens, called Tinyians, build the best house on their planet called Tiny World.
• experiment with different building materials to collect data to see which ones best meet the criteria for building a home on Tiny World.
• test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
Background Research:
You will need to gather background research from the virtual lab to form a good hypothesis. Read the Welcome to Tiny World part of the lab. Use the background information you learn to answer the questions below.
Describe the gravity of Tiny World.
Part 1:
Describe the reason your house will need magnets.
Describe the climate of Tiny World.
Hypothesis:
In this section, include the IF/THEN statements you developed during your lab activity. These statements reflect your predicted outcomes for the experiment.
A If we use _______ to build the roof of the house, then the temperature inside the house will remain cooler.
B If we use_______ to build the walls and floors of the house, then the temperature inside the house will remain cooler.
C If we use ______ to bring electricity into the home, then it will allow electricity to flow into the home at a faster rate.
D If we use_______ to construct the latches on the windows and doors, then the magnetism will keep the latches secure.
Part 2
Procedure:
1. You will test each building material for density, thermal and electrical conductivity, flexibility, and magnetism.
2. Record your observations in the data table provided below.
3. Repeat steps with all test materials.

part 3
Conclusion
Your conclusion will include a summary of the lab results and an interpretation of the results. Please answer all questions in complete sentences using your own words.
1 Using two to three sentences, summarize what you investigated and observed in this lab.
2 What was the independent variable in the lab?
3 What was the dependent variable in the lab?
4 Did each of your experiment results support, or fail to support your four hypotheses? A.
B
C.
D.
5 Why do you think a building material's density is important when building homes or architectural structures?
6 Why wouldn’t you choose wood or aluminum for the latches on your house?
7 Which material has the highest thermal conductivity?
8 Which material has the highest electrical conductivity
9 Based on your data, explain why these materials have the highest thermal and electrical conductivity?
10 Think about where you live now or where you have lived in the past; use complete sentences to describe this environment and the weather.
Answer:
The purpose of the "Measuring Physical Properties Lab Report" is to test the physical properties of different building materials in order to choose the most suitable materials for a new home in Tiny World. The lab objectives include helping the Tinyians build their best house, experimenting with different materials to collect data, and testing each material for density, thermal and electrical conductivity, flexibility, and magnetism.
The background research will provide information about Tiny World, including its gravity, climate, and other relevant details. The hypothesis section requires you to make IF/THEN statements based on the lab activity. For example, IF we use a certain material for the roof, THEN the temperature inside the house will remain cooler.
In part 2, the procedure involves testing each building material for density, thermal and electrical conductivity, flexibility, and magnetism. You need to record your observations in the data table provided.
In part 3, the conclusion should summarize the lab results and provide an interpretation of the results. It also includes answering questions about the independent and dependent variables in the lab, whether the experiment results support or fail to support the hypotheses, and explanations about the importance of density in building materials, why wood or aluminum wouldn't be suitable for latches, and which materials have the highest thermal and electrical conductivity.
Finally, you are asked to describe the environment and weather of a place you have lived in the past or currently live in, using complete sentences.
Hope this helps :)
