Answer:
B. Measures of central tendency
Explanation:
Mean, median and mode are best described as measures of central tendency of a given data set.
Mean is the average of the samples given
Mode is the data point with the most frequent occurrence
Median is the data point that lies in the middle
- All these parameters tells us how far a data point is from the middle or how close they are.
<h2>Hello!</h2>
The answer is: 4.77atm
<h2>Why?</h2>
Since there's a fixed volume, we can use the the Gay-Lussac's Law which stablish a relation between the pressure and the temperature:
<em>P</em> is the volume of the gas
<em>t</em> is the temperature of the gas
<em>k </em>is the proportionality constant
We also have the following equation:
Where:
We are asked to find the pressure in atm, so we must convert 483.73kPa to atm:
Then,
Have a nice day!
First off, you must realize that the phase changes are marked by the points B and D on the graph. They are level because all of the energy (or heat) being added is being consumed by the physical process. So The temperature is increasing before the phase change, and after the phase change. The moments before and after are represented by points A, C, and E.
