<span>The element in a thermostat that is sensitive to temperature changes is mercury. The correct option among all the options that are given in the question is the first option. The other choices are incorrect and can be easily neglected. I hope that this is the answer that has actually come to your help.</span>
According to Dalton's Law of Partial pressure, the pressure exerted by a mixture of non-reacting gases is equal to the sum of their partial pressure.
Mathematically,
Total Pressure = P₍₁₎ + P₍₂₎ + P₍₃₎ + ....... ------(1)
Data given:
Partial pressure of Nitrogen = P₍₁₎ = 587 mmHg
Partial pressure of Oxygen = P₍₂₎ = 158 mmHg
Partial pressure of Argon = P₍₃₎ = 7.00 mmHg
Putting these values in eq 1.
Total Pressure = 587 mmHg + 158 mmHg + 7 mmHg
Total Pressure = 752 mmHg
