Question

1. absolute zero corresponds to a temperature of

(a) ( 0 ^ { circ } k )
(b) ( - 273 ^ { circ } c )
(c) ( 373 ^ { circ } f )
(d) ( 400 ^ { circ } c )

Explanation:

Absolute zero is the lowest possible temperature where nothing could be colder and no heat energy remains in a substance. In the Kelvin scale, it is defined as \(0^{\circ}K\). To convert from Kelvin to Celsius, the formula is \(T_{C}=T_{K}- 273.15\). So \(0^{\circ}K\) is \(-273.15^{\circ}C\approx - 273^{\circ}C\).

Answer:

A. \(0^{\circ}K\), B. \(-273^{\circ}C\)
