Specific Gravity = SG = ρ/ ρ

For the given problem:

m = mass = 18.5g

V = volume = 23.4 ml

Density of reff substance = ρ

We need to find the density of the substance. Density = mass/volume

Mass in kg = 18.5 /1000 = 18.5 x 10

ρ = (18.5/1000) kg / 23.4 ml /

c = 34700/(350 x 151) = 34700/52850 = 0.65657521286 J/(g x ?C)

m =mass=400g

Q = energy = 24000 joules

ΔT = change in temperature = x-20 =(x–20)? C

c = Specific heat =7.5 J/(g?C)

We need to find the final temperature. Now Since Q = cmΔT, therefore ΔT = Q/mc

ΔT =24000/ (400x7.5) =80 ?C.

Final temperature x=80+20 = 100?C.
