WebHeat current i H is defined as the amount of heat Q transferred per unit time t in a given material across a temperature difference at a steady state. i H =dQ/dt. Suppose an object is kept at a temperature difference ΔT and has attained a steady state. Then, for heat conduction, Heat current i H is proportional to the temperature difference ΔT WebThe specific heat of water is 4186 J/g degrees Celsius. Mass of water be 0.7 g. The heat formula is given by: Heat (Q) = 4186 x 60 x 0.7 = 175812 Joules. Heat = 175.812 Kilo Joules. Thus, the heat required to raise the temperature of the water from 30 degrees Celsius to 90 degree Celsius is 175.812 Kilo Joules.
