Answer:

K=18.70kJ

Explanation:

The kinetic energy of an ideal gas is defined as:

K=\frac{3}{2}nRT

Here n is the number of moles of the gas, R is the ideal gas constant and T is the temperature of the gas. So, replacing the given values, we get the kinetic energy of the system:

K=\frac{3(5mol)(8.31\frac{J}{mol\cdot K})(300K)}{2}\\K=18697.5J=18.70kJ

Why do streets and highways have speed limits rather than velocity limits?
andrew11 [14]

They actually DO have velocity limits. There are legal restrictions on both speed and direction.

-- Speeds are limited according to the black numbers on white signs that you see on sign-posts everywhere.

-- Directions are limited by the layout of the pavement and curbs on all the highways, avenues, roads, boulevards and streets, as well as the countless signs that say "One Way", "No Left Turn", "Keep Right", "Keep Left", etc. Violate one of these, and you get nailed as sure as if you had exceeded a posted speed limit.

Imagine a particle that has three times the mass of the electron. All other quantities given above remain the same. What is the
melamori03 [73]

Answer:

The only parameter that changes is mass m

It is only necessary to calculate the ratio Eh/Ee

m_{h}=3m_{e}\\E_{h}=\frac{3m_{e}v^{2}}{2}\\E_{e}=\frac{m_{e}v^{2}}{2}\\\frac{E{h}}{E{e}}=3

The kinetic energy of the heavy paricle is three times the kinetic energy of an electron

The Goodyear blimps, which frequently fly over sporting events, hold approximately 1.65_105ft3 of helium.
Sonbull [250]
Applying the ideal gas equation:
PV = nRT
PV = (mass/Mr)RT
mass = PVMr/RT
mass = (101325 x 4672.2 x 4) / (8.314 x 297)
= 766887.3 kg
= 7.7 x 10⁵ kg
