easy
Calorie is defined as the amount of heat required to raise temperature of $1g$ of water by $1°C$ and it is defined under which of the following conditions
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$
(IIT-2005)
Solution
(a) One calorie is the heat required to raise the temperature of $1 g$ of water from $14.5^{\circ} \mathrm{C}$ to $15.5^{\circ} \mathrm{C}$ at $760 \mathrm{mm}$ of $\mathrm{hg}$
