m = Mass of vinegar / milk

C = Specific heat of vinegar / milk

ΔT = Change in temperature for vinegar / milk

T_i = Temperature of vinegar / milk at room temperature

T_f = Temperature of vinegar / milk after heating

Q = Amount of heat

P = Power of kettle

t = Time of heating

Q = m * C * ΔT

P (watt) * t (s) = 1 (kg) * C * (T_f - T_i)

I'd like to see you try, though.

Some things have a negative heat capacity, for example, stars. If you were to apply heat energy to a star, it would cool down.
