Question

A 10 kg storage battery has an average specific heat of 0.2 kcal/kg°C. When fully charged, the
energy content of the battery is 1 kcal. If the entire energy were used to raise the temperature, then
the temperature would increase by
a)0.2°c
b)0.5°c
c)200°c
d)20°c
pls also give solution ​

Answer 1

Answer:

0.5degrees

Explanation:

H=mS△T[H=1Kcal,m=10Kg,S=0.2Kcal/Kg℃]

⇒1=10×0.2×△T

⇒△T=

10×0.2

1

⇒△T=0.5℃
