Answer:
The value of specific heat of metal = 0.3537
Explanation:
Mass of water = 140 gm = 0.14 kg
Initial temperature of water = 25°c = 298 K
Mass of metal = 108.6 gm = 0.1086 kg
Initial temperature of metal = 100°c = 373 K
After thermal equilibrium the final temperature = 29.6°c = 302.6 K
Apply energy principal
Heat lost by metal = heat gain by water --------- (1)
⇒ Heat lost by metal = ×
× (
-
)
⇒ Heat lost by metal = 0.1086 × × ( 373 -302.6 )
⇒ Heat lost by metal = × 7.64544 KJ -------- (2)
Now
Heat gain by water = ×
× (
-
)
⇒ Heat gain by water = 0.14 × 4.2 × ( 302.6 - 298)
⇒ Heat gain by water = 2.7048 KJ --------------------- (3)
From the energy principal
Equation 2 = equation 3
× 7.64544 = 2.7048
= 0.3537
This is the value of specific heat of metal.
