Question

Mark the point where the temperature of $H_{2}O$ is changing at $4.18J/g^o$C(or $1$ $cal/g^{o}C$)?

• A. A
• B. B
• C. C
• D. D
• E. E

Answer 1

The correct option is C C

At point (C) the temperature of the water is changing at $4.18J/g^{o}C$

The specific heat of liquid water is $4.18J/g^{o}C$.

Thus the section (C) of the curve corresponds to the region where the temperature of the water is heated from $0^{0}C$ to ${100}^{0}C$.

Hence, the correct option is C.
