Question
A block of ice at -10oC is slowly heated and converted to steam at 100oC. Which of the following curves represents the phenomena qualitative ?
Options
A.
B.
C.
D.
Solution
The temperature of ice will first increase from -10o C to 0o C.
Heat supplied in this process will be
Q1 = msi (10)
Where, m = mass of ice
si = specific heat of ice
Then, ice start melting. Temperature during melting will remain constant (0o C).
Heat supplied in this process will be
Q3 = msw(100)
Where, sw = specific heat of water
Finally, water at 100o C will be converted into steam at 100o C and during this process temperature again remains constant. Temperature versus heat supplied graph will be as shown in figure.
