How much heat must be removed to completely freeze 15 kg of water initially at 95°F?...
When 15-kg of some unknown at 180°C is added to 4-kg of water at 20°C the resulting temperature is 60°C. What is the specific heat of the unknown? J Cwater = 4186 kg:K, Lf = 3 For water : Cice = 2100 kg.k - 34 x 105 kg
How much ice is in the final state after 2 kg of ice at -30°C is added to a large quantity of water at 0°C? The final state is ice-water. (The temperature of the ice increases to 0°C and some of the water freezes.) J For water : Cice = 4186 J kg.K If = 3 = 2100 kg.K : Cwater L, = 2.26 x 106 .34 x 10% J kg 9 kg
How much energy is required to heat a 0.3kg package of frozen vegetable juice to 5 degrees celsius if it is initially at -10 degrees celsius. Assume that the vegetable juice is essentially water such that Cice = 2100 kg/Celsius, Lf= 334,000J/kg, and Cwatee = 4186 J/kg Celsius.
How much heat must be removed from 456 g of water at 25.0 degree C to change it into ice at -10.0 degree C? The specific heat of ice is 2090 J/kg K. the latent heat of fusion of water is 33.5 times 10^4 J/Kg, and the specific heat of water is 4186 J/kg K.
