Answer:
35.7kJ
Explanation:
we can calculate the amount of heat energy required , using this formula
Q = mcθ
where.
Q = heat energy (Joules, J)
m = mass of a substance (kg)
c = specific heat capacity (units [tex]Jkg^{-1} C^{-1}[/tex])
θ = change in temperature (Celcius,C or Kelvin K)
Assume Specific heat capacity (c) of water =[tex]4200Jkg^{-1} C^{-1}[/tex]
mass =0.1 kg
[tex]Q=0.1 kg*4200Jkg^{-1} C^{-1}*85C\\=35700J\\=35.7kJ[/tex]
