Answer:
Gases have three characteristic properties: 1. they are easy to compress, 2. they expand to fill their containers, and 3.they occupy far more space than the liquids or solids from which they form. Compressibility. An internal combustion engine provides a good example of the ease with which gases can be compressed.

Answer:
Technician A is correct
Explanation:
The best approach to solve the problem is that of technician A. using a fluorescent die is the easiest and most efficient way to trace leaks with unknown sources. The fluorescent die will simply illuminate the path to the leaking spot in the engine of the car, without any need for much speculations. This makes this method a sure approach.
However, Technician B's approach still has a lot of assumptions factored into the methodology, and would not work properly. It will still require the painstaking attempts trying to make guesses where the oil leak is coming from, which will lead to wastage of time and energy.
This makes Technician A have the right approach to solving the problem
Answer;
-Compass Rose
A symbol on a compass or map that is circular with graded points for the direction is commonly known as a compass rose.
Explanation;
The Earth is a magnet that can interact with other magnets such that, the north end of a compass magnet is drawn to align with the Earth's magnetic field.
A compass rose is a figure on a compass, map, nautical chart, or monument used to display the orientation of the cardinal directions (north, east, south, and west) and their intermediate points. It is a feature on a map that also tells people what direction to go to find certain places on the map
Answer: Option (B) is the correct answer.
Explanation:
When model B shows three dimensional shape of the molecule then it becomes easier to visualize the exact shape or geometry of the molecule as we get to know how atoms are bonded together.
Therefore, with the help of this it would be easy to know the hybridization of molecule. Basically, we will get to know the type of molecule represented by model B.
Thus, we can conclude that the statement Model B shows the three-dimensional shape of the molecule, but Model A does not represents Model B better than Model A.
Answer:
Explanation:
The missing image of the figure slide is attached in below.
However, from the model, it is obvious that it is in equilibrium.
As a result, the relation of the force and the torque is said to be zero.
i.e.
and 
From the image, expressing the forces through the y-axis, we have:
Also, let the force 
be the pivot and computing the torque to determine 
:
Then:
For the force equation:
where:
Then:
