Here is the comparison of the properties of electrons, neutrons and protons:
<span>Electrons are negatively-charged particles and are found outside the nucleus of the atom, They interact with other electrons of other atoms that result to different properties of atoms. They also determine the charge of the atom, or more preferably, the ion. For a neutral atom, they have the same number as that of the protons. Protons are positively-charged particles and are found inside the nucleus along with the neutrons. Protons and neutrons are collectively called nucleons. Protons determine the atomic number of the atom. Neutrons, on the other hand, are neutrally-charged particles and are found inside the nucleus. Along with the proton, they constitute the mass of the whole atom. Atoms of the same element but with a different number of neutrons are called isotopes.</span>

Question 1 of 7What is the change in internal energy if 90 J of thermal energy is added to asystem, and the system does 30 J of
Dmitriy789 [7]

Given:

The thermal energy added to the system is Q = 90 J

The work done by the system on the surroundings is W = 30 J

To find the change in internal energy.

Explanation:

According to the first law of thermodynamics, the change in internal energy can be calculated by the formula

\Delta U=\text{ Q-W}

On substituting the values, the change in internal energy will be

\begin{gathered} \Delta U\text{ =90-30} \\ =60\text{ J} \end{gathered}

Final Answer: The chage in internal energy is 60 J (option D)
