A liquid-in-glass thermometer should quickly register temperature changes. This is achieved by choosing a liquid that
is opaque
has high density
has regular expansion
has a high thermal conductivity
can wet glass
ব্যাখ্যা
The liquid having a higher thermal conductivity means that the liquid allows heat to pass through itself quickly hence a shorter time to respond.
