تحديد الحرارة النوعية للماء المقطّر

m_w = Mass of water

C_w = Specific heat of water

ΔT_w = Change in temperature for water

T_i = Temperature of water at room temperature

T_f = Temperature of water after heating

Q = Amount of heat

P = Power of kettle

t = Time of heating

Q = m_w * C_w * ΔT_w

P (watt) *t (s) = 1 Kg * C_w * (T_f - T_i)
