Answer: Option (a) is the correct answer.
Explanation:
Specific heat is defined as the heat energy necessary to raise the temperature of a 1 kg of substance by one degree celsius.
For example, specific heat of water is 4.18 J [tex]kg^{-1} ^{o}C^{-1}[/tex]
Whereas heat of vaporization is the energy absorbed at a certain temperature to convert a unit mass of a substance from liquid to vapor state.
Hence, we can conclude that Sascha is observing the property that water has a high specific heat capacity.
