The boiling point is defined as the temperature at which the pressure of the vapor of the liquid is equivalent to the external atmospheric pressure surrounding the liquid. Therefore, the boiling point of the liquid is dependent on the atmospheric pressure.

Based on this, the vapor pressure of cyclohexane at 81 degrees celcius will be equal to atmospheric pressure (based on barometric readings)<span />

Technician A says voltage will not exist between any two points in a circuit if the potential is zero. Technician B says corrosi

nordsb [41]

Answer:

<u>Option-(A):</u> If there is no potential or we can say the difference in total amount of charges present inside the system then the voltage's value wont be greater then "0" inside the circuit or system.

Explanation:

While, the circuit or system requires the difference in total amount of energy that each atom on that spot has, as this potential energy difference or the total number of charges difference contribute to having a more specified manner of voltage,v in that system. And thus the flow of charges,Q from a point of origination or source towards a region of lower energy is all due to this difference in potential.

1. A gas is kept at a pressure of 22Kpa and a temperature of 287K. What will

Ann [662]

Answer:

New pressure (P2) = 22.92 Kpa (Approx)

Explanation:

Given:

Old pressure (P1) = 22 Kpa

Temperature (T1) = 287 K

Temperature (T2) = 299 K

Find:

New pressure (P2)

Computation:

P1 / T1 = P2 / T2

22 / 287 = P2 / 299

New pressure (P2) = 22.92 Kpa (Approx)
