Physics Question on thermal properties of matter
Two substances A and B of the same mass are heated at a constant rate. The variation of temperature θ of the substances with time t is shown in the figure. Choose the correct statement
A
Specify heat of A is greater than that of B
B
Specify heat of B is greater than that of A
C
Both have some specific heat
D
None of the above is true
Answer
Specify heat of A is greater than that of B
Explanation
Solution
the melting point of substance A is 60°C and the melting point of substance B is 20°C. It is given that substance A takes 4 minutes for fusion (melting) and substance B takes 2.5 minutes.
The correct answer is option (A): Specify heat of A is greater than that of B
