Answer: C. Gas particles move faster and farther apart at higher temperatures.
Explanation:
The options include:
A. the number of gas particles increases at higher temperatures
B. the number of gas particles decreases at higher temperatures
C. gas particles move faster and farther apart at higher temperatures
D. gas particles move more slowly and get closer together at higher temperatures
The statement that describes how the outcome (dependent) variable changes as a result of the changes made to the tested (independent) variable is that gas particles move faster and farther apart at higher temperatures.
It should be noted that the particles in the gases will collide more frequently with one another because of the shorter space that is between them.
The increase in the temperature will bring about a faster movement of the particles which in turn, brings about a rise in the diffusion rate and also the collision rate.
Answer:
A. Designing a device that is biologically compatible
Explanation:
Explanation:
Volume of the stock solution is 
= ?
Initial concentration of ampicillin is 
= 100 mg/ml
Final volume (
) = 30 ml
Final concentration of ampicillin (
) = 25 mg/ml
Therefore, calculate the volume of given stock as follows.
= 
Now, putting the given values into the above formula as follows.
=
= 
= 7.5 ml
Now, we will calculate the volume of water added into it as follows.
Volume of water added = 
= 30 ml - 7.5 ml
= 22.5 ml
Thus, we can conclude that required solution is 22.5 ml of deionized water.
