Answer: The amount of energy consisted in the molecules determines the state of matter.
Explanation:
As we know that force F makes an angle of 60 degree with X axis
so the X component is given as

now we have


Similarly we know that force F makes an angle of 45 degree with Y axis
so the X component is given as

now we have


Now for the component along z axis we know that

now plug in all components





B when is spins it means its rotating east and west directions
M = molar mass of the helium gas = 4.0 g/mol
m = mass of the gas given = 18.0 g
n = number of moles of the gas
number of moles of the gas is given as
n = m/M
n = 18.0/4.0
n = 4.5 moles
P = pressure = 2.00 atm = 2.00 x 101325 Pa = 202650 Pa
V = Volume of balloon = ?
T = temperature = 297 K
R = universal gas constant = 8.314
Using the ideal gas equation
P V = n R T
(202650) V = (4.5) (8.314) (297)
V = 0.055 m³
So the pH level of regular water is about 7.0 so since it is 7.9, it means the water is a little more basic
