How will the behavior of the gases in the piston chamber change if more pressure is applied to the piston?

allsm [11]

Here molecules of gas remains constant. If more pressure is applied to the piston, gaseous molecules will come closer to each other. Hence their volume decreases and density increases. Hope this helps you.

A pure lead bar 10 cm long is maintained with one end at T=300 K and the other at 310 K. The thermoelectric potential difference

dangina [55]

Answer:1.28v/k

Explanation:

Thermoelectric power is the same as Seebeck coefficient.

So the formula is S =Vemf/Th - Tl

= 12.8/310-300

S= 12.8/10

=1.28V/T

Gaseous helium is in thermal equilibrium with liquid helium at 6.4 K. The mass of a helium atom is 6.65 × 10−27 kg and Boltzmann

chubhunter [2.5K]

Answer:

162.78 m/s is the most probable speed of a helium atom.

Explanation:

The most probable speed:

$v_{mp}=\sqrt{\frac{2K_bT}{m}}$

$K_b$ = Boltzmann’s constant = $1.38066\times 10^{-23} J/K$

T = temperature of the gas

m = mass of the gas particle.

Given, m = $6.65\times 10^{-27} kg$

T = 6.4 K

Substituting all the given values :

$v_{mp}=\sqrt{\frac{2\times 1.38066\times 10^{-23} J/K\times 6.4 K}{6.65\times 10^{-27} kg}}$

$v_{mp}=162.78 m/s$

162.78 m/s is the most probable speed of a helium atom.
