The Kelvin Scale

In a problem,...

Question

In a problem, we have a situation,
P1V1/T1=P2V2/T2
In the question,T1 and T2 are given in degree Celsius,
V1 ,V2 and P1 are also given,
In order to find P2,
Is it necessary to convert T1 and T2 to Kelvin scale?

Solution

The explanation is as follows.

In the given situation described in your question, it is necessary to take temperature in kelvin scale reading.
Since absolute values of temperature are used, this make the concersion necessary.

Then, when it is not necessary?
So if there is a difference of temperature used or taken in any question. It is not necessary to make the conversion. As the difference in two temperature on both kelvin scale and Celsius scale is same.
But if the case is with Fahrenheit scale then it requires proper conversions.

Hope it answers your question.
All the best!

Q. A point moves with uniform acceleration and

v_{1}, v_{2} a n d v_{3}

denote the average velocities in the three successive intervals of time

t_{1}, t_{2} a n d t_{3}

Which of the following relations is correct

Two thermally insulated vessels $1$ and $2$ are filled with air at temperature ( $T_{1}$ , $T_{2}$ ), volume ( $V_{1}$ , $V_{2}$ ) and pressure ( $P_{1}$ , $P_{2}$ ) respectively. If the value joining the two vessels is opened, the temperature inside the vessel at equilibrium will be

\frac{P_{1} V_{1}}{T_{1}} = \frac{P_{2} V_{2}}{T_{2}}

Two thermally insulated vessels 1 and 2 are filled with air at temperatures $(T_{1}, T_{2})$ , volume $(V_{1}, V_{2})$ and pressure $(P_{1}, P_{2})$ respectively. If the valve joining the two vessels is opened, the temperature inside the vessel at equilibrium will be
