The urms of h2 molecules at 273k is 1.84×103m/s.part aat what temperature is urms for h21.8 times greater than this value?

The formula for calculating urms is given as:

urms = sqrt (3 R T / M)

where,

R is gas constant = 8.314 J / mol K

T is absolute temperature = ?

M is molar mass of H2 = 2 x 10^-3 kg/mol

 

Calculating for T:

1.8 * (1.84×10^3) = sqrt (3 * 8.314 * T / 2x10^-3)

<span>T = 879.59 K      (ANSWER)</span>

Water at a rate of 45,500 kg/h is heated from 80 to 150°C in a heat exchanger having two shell passes and eight tube passes with
Vlad [161]

Answer:

U = 129.053 KJ/m².h

Explanation:

overall heat transfer coefficient (U):

U = (<em>m</em>Cp(ToutH2O - TinH2O))/[A((ToutAir - TinH2O)-(TinAir - ToutH2O))/(Ln(ToutAir - TinH2O)/(TinAir - ToutH2O))]

∴ A = 925 m²

H2O:

∴ mass flow H2O (<em>m</em>) = 45500 Kg/h

∴ Cp H2O = 4186 J/Kg°C

∴ Tin = 80°C

∴ Tout = 150°C

Air:

∴ Tin = 350°C

∴ Tout = 175°C

⇒ U = ((45500Kg/h)(4186J/Kg°C)(150-80))/(925m²)[((175-80)-(350-150))Ln((175-80)/(350-150))]

⇒ U = (1.333 E10 J/h)/(925m²)[(-150)Ln(0.475)]

⇒ U = 129052.73 J/m².h = 129.053 KJ/m².h

Answer:

D or A

<em>But I do know...</em>

It's because new strains of the virus are constantly appearing and evolving, so the vaccine must change along with them.

A photon has 8.0 × 10–15 J of energy. Planck’s constant is 6.63 × 10–34 J•s. What is the frequency of the photon
german
The formula is:
frequency * h (Planck's constant) = Energy
So, to find frequency you need just divide energy by the constant:
frequency = (8 * 10^-15 J) / (6.63 * 10^-34 J*s) = 1.2 * 10^19 1/s or 1.2 * 10^19 Hz

An object will _____ if the weight of the liquid displaced is less than the weight of the object.
Tpy6a [65]

I am not exactly sure the answer that you are looking for, but I will guess on what you might be looking for. If the weight of an object is greater than the weight of the liquid it's being put into, the object will sink. Although, it isn't necessarily just based upon weight, it is more dependent on density to decide if it'll float or sink.
