Answer:
Correct answer:
As the temperature increases, the kinetic energy of the molecules increases.
Explanation:
The relation between kinetic energy and temperature in an ideal gas which we will take as an example is given by the following formula:
Ek = 3/2 N k T ,
where N is the total number of molecules a k is a Boltzmann constant.
If we assume that the total number of molecules is a constant, kinetic energy only depends on temperature.

For the answer to the question, ergonomics<span> is the science of fitting the job to the worker. When there is a mismatch between the physical requirements of the job and the physical capacity of the worker, work-related musculoskeletal disorders (MSDs) can result. Ergonomics is the practice of designing equipment and work tasks to conform to the capability of the worker, it provides a means for adjusting the work environment and work practices to prevent injuries before they occur.</span>
A roller coaster accelerates from an initial velocity of 6.0 m/s to a final velocity of 70 m/s over 4 seconds. whats the acceleration
<span>The complete question is:
</span><span>If a liquid is sealed in a container and kept at constant temperature, how does its vapor pressure change
</span>a. it continues to steadily increase
<span>b. it increases at first, then remains constant </span>
<span>c. it increaees at first, then decreases </span>
<span>d. it continues to steadily decrease
</span>
I believe the correct answer is option B. The vapor pressure change would be that it increases at first, then remains constant. <span>More particles escape the liquid and go into the vapor phase at first. But eventually, the number of escaping particles equals the number of particles going back into the liquid.</span>
