Answer:

20KJ

Explanation:

We know that heat required to raise the temperature of substance is given by

thermal energy Q= mass(m) × specific heat capacity(c) × change in temperature.(ΔT)

Q = mcΔT

given data: mass m = 2kg , c = 2000j/Kg°C and ΔT = 120-20 =100°C

Therefore, Q = 2×2000×100 = 20000 J = 20KJ

Hence, 20KJ heat is required to to heat 2 kg of cooking oil with a specific heat capacity of 2000 from 20 to 120 [ Units have been assumed as per convenience)
