Because gases flow easily. A hot batch of gas can rise through
the surrounding gas a lot easier than, say, a hot batch of mud can
rise through the surrounding mud.
Answer:
All of the above
Explanation:
To ensure the ball go to where we expected it go
Answer: Reflected
Explanation: Color Gradient refers to the variety of position dependent (as the vary with position) colors which are used to fill a region. Gradient is a mixture of two or more colors. This blend of colors adds depth to the design.
Types of color gradient are
- Linear: The color blends in a straight from starting to ending point
- Radial: The color transitions from starting point to ending a circular pattern.
- Angle: It glides counterclockwise around starting point.
- Diamond: It makes a diamond shape from starting point and its ending point is one corner of diamond.
- Reflected: In this color gradient type symmetric linear gradient gets mirrored on either side of the starting point. This type of color gradient can be used to depict a lead pipe.
Answer:
C-D
Explanation:
As you can see from the graph, the distance from A to B was from 0 m to 6 m in a duration of 3 seconds.
Divide 6 meters by 3 seconds to find the speed:
6 ÷ 3 = 2 m/s
B-C is not moving due to a straight line as said in the graph, so speed is
0 m/s.
There is also C-D since the car traveled from a distance of 9 meters
(6 -(-3) = 9) in 3 seconds too. (NOTE: The graph line going down does not mean it is slowing down, but rather going to a certain distance like going backwards)
Divide 9 meters by 3 seconds to get the speed:
9 ÷ 3 = 3 m/s
Between A-B, B-C, and C-D, C-D has the fastest speed recorded with 3 m/s.
A-D does not count here as the line has no connection between point A and point D.

Answer: 4.358 kPa
Explanation:
The gas is contained within a rigid container, so the volume of the gas is constant. Therefore, we can use Gay-Lussac's law, which states that:
"for a gas kept at constant volume, the pressure and the absolute temperature are directly proportional"
In formulas:
where:
is the initial pressure
is the initial temperature
is the final pressure
is the final temperature
Substituting the numbers into the equation, we find
