Answer:
Explanation:
Potential energy builds as the coaster is going up the loop-the-loop and converts to kinetic energy on the way down and out of the loop-the-loop. The potential energy of the coaster is at its lowest and the kinetic energy is at its highest as the coaster moves in the lowest point of the loop-the- loop.
Answer:
2.3 L
Explanation:
when you have this eqaution you use P1V1T2=P2V2T1.
since you are looking for volume of gas cylinder that means you are looking for V2.
so you have your given P= 1.0 atm, V=2.5L, T=298K.
They ask you to use STP or standard pressure and temperature.
STP P= 1atm, STP T=273 K
so you are looking for V2 meaning you are going to get V alone so your new equation is P1*V1*TS/ P2* T1= V2
so you now substitue so its now 1*273*2.5/ 1* 298= V
682.5/ 298= V
Lastly V= 2.2902 and you round to tenths so now you have
V= 2.3 L
Explanation:
It is known that for
, ppm present in 1
are as follows.
1
= 0.494 ppm
So, 150
= 
= 0.15 
Therefore, calculate the equivalent concentration in ppm as follows.

= 0.074 ppm
Thus, we can conclude that the equivalent concentration in ppm at STP is 0.074 ppm.
The answer is 329. Because 273 + 56 = 329.
In this case, we can say that water is the solvent. Solvent by definition are the part of the solution that is present in the largest amount. The fruit juice are all dilute by the water. Everything else in the fruit juice can be called the solute, they are what is "dissolved" in the solvent (sugar, fruit juice, etc.).
