To treat a 67.9 kg patient, what is the minimum amount of ice (at 0∘C) that you need in the bath so that its temperature remains at 0∘C? The specific heat of the human body is 3480 J/(kg⋅C∘), and recall that normal body temperature is 37.0 ∘C.
Express your answer in kilograms.
Compute the total heat required to convert 0.125 Kg of ice at –125°C to steam at 125 °C.
(Cice = 2090 J/kg.°C, Cwater = 4186 J/kg.°C, Csteam = 2010 J/kg.°C,
Lf = 3.33 × 105
J/kg, Lv = 2.26 × 106
J/kg.)
Sketch the flow chart (diagram ) and compute the total heat required to convert 550 g of ice at - 25 degrees * C to steam at 145 ° C . (Cice=2090 J/kg.^ C , Cwater=4186 Jkg.^ C,Csteam=2010 J/kg.^ C Lf=3.33*10^ 5 J/kg,Lv=2.26*10^ 6 J/kg.)
