Q410
The specific heat of saturated water vapour at 100°C is
A.
∞
B.
-ve
AnswerC.
0
D.
+ve
Answer: Option B
Solution
Answer: Option B
Solution:
The specific heat is the amount of heat required to change the temperature of the substance from by unit degree. Since during saturated conditions latent heat conversion only takes place and temperature remains constant the situation appears like the system is of infinite strength and there is no change in thermal energy and hence the heat capacity is infinity.
