Answer:
The energy change for the given system: <u>ΔE = 45 J</u>
Explanation:
According to the<u> First Law of thermodynamics</u>, the energy can't be created or destroyed and can only be converted into other forms.
ΔE = Q - W ......equation 1
Given: ΔE is the change in the internal energy
Q is the heat absorbed by the system
W is the work done by the system
<u>Given</u>: Q = = 533 J, W = 488 J, ΔE = ?
Using equation 1, to calculate the change is the internal energy (ΔE),
ΔE = Q - W = 533 J - 488 J = 45 J
<u>Therefore, the energy change for the given system: ΔE = 45 J</u>

Answer:
The correct statement should be The energies of electron are <em>quantized</em> when <em>they are bounded to an atom.</em>
In Quantum Mechanics The term Quantization used to measure the physical entities having certain discrete value. When we say energies of electron are <em>quantized</em> <em>that means it have some specific values</em> that are allowed, that is not continuous range of values.
