How many kiloJoules of energy are released when 1600.g of water cools from 80.0^º C to 60.0^º C? A)32.0 kJ B)382 kJ C)515 kJ D)134 kJ

Question

Quizplus · Accepted Answer

The energy released (q) can be calculated using the formula q = mcΔT, where m is the mass of the water (1600 g or 1.6 kg), c is the specific heat capacity of water (4.184 kJ/kg·ºC), and ΔT is the change in temperature (20ºC). Plugging in the values: q = 1.6 kg * 4.184 kJ/kg·ºC * 20ºC = 133.888 kJ, which rounds to 134 kJ.
