Three objects of different materials but of equal masses are kept in a heating chamber where all three receive energy at a same constant rate. During heating each object starts with liquid state and finally gets converted in the gaseous state. For each of the object, temperature T versus time t graph is plotted, as shown and marked I, II and III.
II. If Ll, Lll and Llll represent their respective latent heat of vapourization then
A
Llll>Lll>L
B
Ll>Llll>Lll
C
LII> LIII> LI
D
LII> LI> LIII
Answer
LII> LIII> LI
Explanation
Solution
Object II remains in liquid state for maximum time, receiving energy at constant rate. It takes maximum energy to get vapourized.
