Work equals Force times Distance. So Work = 250 Newton’s * 5 meters Work = 1,250
10 joules of work is done by the object
This question involves the concepts of work done, pressure, and temperature.
The work done per mol of the air is "-724.71 J/mol".
Using the given formula for work done:

where,
W = work done per mol = ?
R = universal gas constant = 8.314 J/mol.k
T = absolute temperature = 30°C + 273 = 303 k
P₁ = initial pressure = 30 KPa
P₂ = final pressure = 40 KPa
Therefore,

<u>W = -724.71 J/mol</u>
<u></u>

Distance can be equal to displacement ... if the motion is all in a straight line ... but distance can never be greater than displacement.
The best explanation of the observation of the researcher is that some of the energy is converted into thermal energy (option C).
<h3>How does energy transfer?</h3>
Energy, according to the law of conservation of energy, cannot be created nor destroyed but transformed.
According to this question, a researcher found that the amount of light energy produced in a neon lighted sign was less than the amount of electrical energy used.
This suggests that some of the energy is converted into thermal energy.
