The specific heat of water is 4.2 kj/kg.°c. when 400 kj of heat is added to 12 kg of water at 2°c, its final temperature is celsius answer

Try this solution:

given: 4200 (J/kg*°C)=C; 400kJ=4*10⁵ (J)=Q; 12 kg=m; 2 °C=t₀.

1. The basic formula is: t=t₀+Δt.

To find Δt: Q=C*m*Δt; ⇒Δt=Q/(Cm).

The final formula is:

t=t₀+ Q/(Cm).

2. Using the final formula:

≈9.9365 °C

i just did an experiment like this in my science class. also the answer is yes, it will get separated because they are two opposites meaning if they are opposite they can not attract.

hope this .!
