mass 100kg the temperature rises by 1k
mass 1kg, the temperature by 1000K
mass 1kg, the temperature rises by 1K
mass 100kg, the temperature rises by 1000k
Correct answer is C
The specific heat capacity of a body is the heat energy required to raise a body of mass 1kg through a temperature of 1K.
PV = \(\frac{constant}{T}\)
\(\frac{P}{T} = Constant\)
\(\frac{P}{V} = \frac{constant}{T}\)
\(\frac{I}{T} = \frac{constant}{PV}\)

-25oC
-20oC
20oC
25oC
Correct answer is A
\(\frac{440 - 380}{680 - 380} = \frac{0 - x}{100 - x}\)
= -25oC
