An ideal gas initially at 275 k undergoes an isobaric expansion at 2.50 kpa. the volume increases from 1.00 m3 to 3.00 m3 and 11
1 answer:
The transformation is isobaric (constant pressure), so the work done by the gas is the product between its pressure and the variation of volume:
The heat transferred to the gas is
So we can use the first law of thermodynamics to compute the variation of internal energy of the gas:
where the positive sign means the internal energy of the gas has increased.

Answer:
this answer you question
The mass of the ion is 5.96 X 10⁻²⁵ kg
<u>Explanation:</u>
The electrical energy given to the ion Vq will be changed into kinetic energy
As the ion moves with velocity v in a magnetic field B then the magnetic Lorentz force Bqv will be balanced by centrifugal force .
So,
and
Right from these eliminating v, we can derive
On substituting the value, we get:
m = 5.96 X 10⁻²⁵ kg.
