When two objects A and B are supplied with the same quantity of heat, the temperature change in A is obtained to be twice that of B. The mass of A is half that of B. The ratio of the specific heat capacity of A to B is
- 1 : 4
- 4 : 1
-
1 : 1
- 2 : 1
The correct answer is: C
Explanation
θA = 2θ\(_{B}\),
| m\(_A\) | = | 1
2 |
m\(_B\) |
H = MCθ
m\(_A\)c\(_A\)θ\(_A\) = m\(_B\)c\(_B\)θ\(_B\)
( 1/2 m\(_B\))C\(_A\) (2θ\(_B\)) = m\(_B\)c\(_B\)θ\(_B\)
| C\(_A\)
C\(_B\) |
= | 1
1 |
⇒ 1 : 1
