Answer:
As altitude increases, the amount of gas molecules in the air decreases the air becomes less dense than air nearer to sea level.
Explanation:
Answer:
The dynamic viscosity of the liquid is 0.727 kg/m*s
Explanation:
In the equation for that viscosimeter, ν = KR⁴t, <u>the terms K and R are not dependent on the liquid that is being tested</u>, unlike ν and t.
Using that equation and the data given in the problem, we can calculate the product of K and R⁴.
1.19*10⁻³m²/s = (KR⁴)* 1430 s
KR⁴=8,32*10⁻⁷m²/s²
We can now calculate the<em> </em><u><em>kinematic</em></u> viscosity of the unknown liquid.
ν=8,32*10⁻⁷m²/s²*900s
ν=7.49*10⁻⁴m²/s
The relationship between the <em>kinematic</em> viscosity and the <em>dynamic</em> viscosity is given by the equation μ=ν * ρ, where μ is the dynamic viscosity and ρ is the density. Thus:
μ=7.49*10⁻⁴m²/s * 970 kg/m³
μ=0.727 kg/m*s
Answer:
Non-equilibrium thermodynamics is a branch of thermodynamics that deals with physical systems that are not in thermodynamic equilibrium but can be described in terms of variables (non-equilibrium state variables) that represent an extrapolation of the variables used to specify the system in thermodynamic equilibrium.

Answer:
3.990225 grams
Explanation:
<u>Remember</u>: Morality = Moles/Liters
<u>And you are given:</u>
100 mL and 0.25
<u>what you want:</u>
Grams
SOOOO.....
convert the 100 ml to L
100 / 1000 = .1 L
now that you have Liters and Morality put it into the equation
0.25 M = Moles/ .1 L
0.25 * .1 L = .025 moles
now you take this and turn it into grams
0.025 moles / molar mass = grams
0.025 moles / 159.609 g = 3.990225 grams
