easy
$1g$ પાણીનું તાપમાન $1°C$ વધારવા માટે જરૂરી ઉષ્માને કેલરી તરીકે દર્શાવવામાં આવે છે,તો તેમાં કઈ પરિસ્થિતિ હોવી જોઈએ ?
A
From $14.5°C$ to $15.5°C$ at $760\, mm$ of $Hg$
B
From $98.5°C$ to $99.5°C$ at $760\, mm$ of $Hg$
C
From $13.5°C$ to $14.5°C$ at $76\, mm$ of $ Hg$
D
From $3.5°C$ to $4.5°C$ at $76 \,mm$ of $ Hg$
