A) less than zero
B) zero
C) slightly greater than zero
D) infinite
Correct Answer: D
Solution :
During conversion of water into steam, temperature remains constant \[(\Delta \theta =0)\] For phase conversion \[\Delta Q=mL=\,ms\,\,\Delta \theta \] or \[s=\frac{L}{\Delta \theta }=\frac{L}{0}=\infty \] \[[\because \,\,\,L\ne 0]\] where, L is latent heat of steam.
