B.The work done is equal to the change in heat energy.
C.The work done is equal to change in entropy.
D.The work done is equal to the change in pressure.
For an isothermal process, the work done by or on a system of ideal gas is equal to the change in heat energy. The correct option is B.
The process in which the temperature remains constant and other physical quantities are variable, is called the isothermal process.
From the first law of thermodynamics, the work done is the difference between heat supplied and change in internal energy of the system.
W = ΔQ - ΔU
For isothermal process, change in internal energy will be zero.
So, work done is equal to the change in heat energy.
Thus, the correct option is B.

B. contains negatively charged particles.
C. has a negative charge.
D. has a positive charge
The particles that make up the nucleus of an atom are protons and neutrons.
The nucleus of an atom is composed of two main types of subatomic particles: protons and neutrons. Protons have a positive electric charge, while neutrons have no electric charge, making them neutral. These particles are relatively heavy compared to electrons, which orbit the nucleus.
The protons and neutrons are held together tightly in the nucleus by a strong force called the nuclear force or strong nuclear force. This force overcomes the repulsive force between positively charged protons, keeping the nucleus stable.
The number of protons in the nucleus determines the element's identity. For example, if an atom has one proton, it's hydrogen; if it has six protons, it's carbon, and so on. This number is called the atomic number. The sum of protons and neutrons in the nucleus is called the mass number.

The exchange particles you are talking about are probably the gauge bosons. They are elementary bosons, meaning that they are elementary particles making part of the standard model and they have integer spin. There are four of them: The photon, the gluon, the W+ and W- bosons and the Z boson. The photon basically is the particle of light being an excitation, if you will, of the electromagnetic field so that is mediates the electromagnetic force. The only thing that differs from long range photons (light) is that they are what is called virtual photons but that is for another subject. Then you have the gluons that come in 8 varieties and their role is to interchange the color charge in between quarks so that it mediates the strong nuclear force, the force that keeps quarks bounded into protons. And then finally there are the W+, W- and Z bosons that mediates this time, the weak nulear force, the force that allows protons to coexist in the nucleus of atoms with neutrons. I hope that helped you, but as i usually do, i tried to simplify my answer beacause i could have written a lot mor about that!
