The change in temperature (ΔT) : 56.14 ° C

Further explanation

Given

Cereal energy = 235,000 J

mass of water = 1000 g

Required

the change in temperature (ΔT)

Solution

Heat can be formulated :

Q = m . c . ΔT

c = specific heat for water =  4.186 J / gram ° C

235000 = 1000 . 4.186 . ΔT

[tex]\tt \Delta T=\dfrac{235000}{1000\times 4.186}=56.14^oC[/tex]
