Answer:
D. demand; increased
Explanation:
Demand is how much people want it.
The gas is in a rigid container: this means that its volume remains constant. Therefore, we can use Gay-Lussac law, which states that for a gas at constant volume, the pressure is directly proportional to the temperature. The law can be written as follows:

Where P1=5 atm is the initial pressure, T1=254.5 K is the initial temperature, P2 is the new pressure and T2=101.8 K is the new temperature. Re-arranging the equation and using the data of the problem, we can find P2:

So, the new pressure is 2 atm.
Answer:
It covers distance of 9.15 football fields in the said time.
Explanation:
We know that

Thus distance covered in blinking of eye =

Thus no of football fields=
