Answer 1

Answer:

$a)the \: temperature \: at \: which \: a \: liquid \: starts \: to \: boil \: is \: called \: boiling \: point$

$b)The Kelvin degree is the same size as the  Celsius degree and the  boiling point of water  (100°C), correspond to 373.15°K, respectively. \: \: \:$

$c) \: it \: do \: not \ \: have \: any \: change$

$d)The bulb of the thermometershould be kept about 4-5 cm above the surface of water. Pieces of pumice stoneshould be added to water before heating to avoid bumping. Heating of watershould be done by rotating the flame \: \: \:$
