Question

The plotted data is extrapolated to what temperature?

A) -160°C
B) 0°C
C) -273°C
D) 600°C

Answer 1

The plotted data is extrapolated to a temperature of -273°C, known as absolute zero, which is the theoretical point where all molecular motion stops. Hence, option (C) is correct.

Step-by-step explanation:

The plotted data is extrapolated to a temperature of -273°C. This temperature is known as absolute zero, where all molecular motion ceases. The significance of this temperature has been recognized since the 19th century. It marks the theoretical limit at which gases have zero volume due to the lack of thermal energy for molecular movement.

This is also the temperature where the pressure of gases extrapolates to zero, as noted by various scientists. The concept of absolute zero is a key component in thermodynamics and is independent of the nature of the gas. Therefore, the correct answer is option (C).
