5 0

<u>Answer:</u> Electron has almost no mass.

<u>Explanation:</u>

Mass is defined as the actual matter that is contained in a substance. At an atomic level, it is expressed in atomic mass units.

The given options are the 3 subatomic particles.

Mass of the given subatomic particles are:

Proton = 1.007276u

Neutron = 1.008664u

Electron = 0.0005485u

Mass of neutron is slightly more than the mass of proton.

From the above information, it is visible that electron has a negligible mass.

Hence, the correct answer is electron.

1. A gas expands and does p-v work on the surroundings equal to
azamat

The change in energy of the system : -63 J

<h3>Further explanation</h3>

Given

279 J work

216 J heat

Required

The change in energy

Solution

Laws of thermodynamics 1

ΔU=Q+W

Rules :

  • receives heat, Q +  
  • releases heat, Q -  
  • work is done by a system, W -  
  • work is done on a system, W +  

a gas work on the surrounding : W =-279 J

a gas absorb heat from surrounding : Q = +216 J

Internal energy :

= -279+216

= -63 J
