Idk why are they important?
Answer:
The answer is cold fronts, wind shear, occluded fronts, and mesocyclones. I got it right on USATESTPREP. What was missing is occluded front. Give me brainliest please if this helped.
Have a wonderful day!
The change in temperature had the greatest effect at changing the volume of the balloon.
<h3>What are the gas laws?</h3>
The gas laws are used to describe the parameters that has to do with gases.
Given that;
P1 = 98.5 kPa
T1 = 18oC or 291 K
V1 = 74.0 dm3
P2 = 7.0 kPa
V2 = ?
T2 = 18oC or 291 K
P1V1/T1 = P2V2/T2
P1V1T2 =P2V2T1
V2= P1V1T2/P2T1
V2 = 98.5 kPa * 74.0 dm3 * 291 K/ 7.0 kPa * 291 K
V2 = 1041.3 dm3
When;
V1 = 1041.3 dm3
T1 = 291 K
V2 = ?
T2 = 80oC or 353 K
V1/T1 = V2/T2
V1T2 = V2T1
V2 = V1T2/T1
V2 = 1041.3 dm3 * 353 K/291 K
V2 = 1263 dm3
The change in temperature had the greatest effect at changing the volume of the balloon.
Given that
V1 = 100 cm^3
T1 = 273 K
P1 = 1.01 * 10^5 Pa
V2 = ?
P2 = 3.00 x 10^-4 Pa
T2 = -180oC or 255 K
V2= P1V1T2/P2T1
V2 = 1.01 * 10^5 Pa * 100 cm^3 * 255 K / 3.00 x 10^-4 Pa * 273 K
V2 = 3.14 * 10^10 cm^3

Answer:
option A is the most supported hypothesis by astronomers
2moles
1.20moles
0.5mole
Explanation:
Given parameters:
Mass of He = 8g
Mass of Zn = 78g
Volume of oxygen gas= 11.2L
Unknown:
Number of moles of He, Zn = ?
Number of moles of oxygen gas = ?
Solution;
Number of moles of substances is given as :
Number of moles =
molar mass of He = 4g/mol
molar mass of Zn = 65.4g/mol
Number of moles of He = = 2moles
Number of moles of Zn = 1.20moles
For gases at STP;
Number of moles =
Number of moles = = 0.5mole
