Gas pshort articles move randomly (both rate and direction, as vector)
Median velocities of gases deserve to be expressed as root-mean-square velocity. (V rms)
R = gas continuous, 8.314 J / mol K
T = temperature,
Mm = molar mass of the gas particles
μ rms = root expect square velocity of Gas Pposts.
You are watching: Calculate the rms speed of an oxygen gas molecule, o2, at 35.0 ∘c .
From this equation reflects that the velocity of the gas is inversely proportional to the molar mass of the gas particles
μ ≅ 1 / mm
So that the better the molar mass of the gas pwrite-ups, the smaller sized the speed (the slowest)
Oxygnlinux.org gas molecule, O₂ has a molar mass: 0.032 kg / mol
T = 35 C + 35 + 273 = 308 K

Whnlinux.org 3000 grams of water is cooled from 80.0 c to 10.0 c, how much power is released
877800 Joules of nlinux.orgergy is released
mass m = 3000 g
initial temperature = 80 c
Final temperature = 10 c
Change in temperature ΔT = 80 - 10 = 70 c
Heat H = ?
The partnership in betwenlinux.org these parameters is provided by;
H = mcΔT
Wbelow c = certain heat capacity = 4.18 J/gc
H = 3000 * 4.18 * 70 = 877800 Joules
