Question

Steam can cause more serious burns than water at the same temperature. Here we examine this effect quantitatively, noting that flesh becomes badly damaged when its temperature reaches 50.0 C a)Calculate the heat released as 13.0g of liquid water at 100C is cooled to 50.0C . b)Calculate the heat released when 13.0g of steam at 100C is condensed and cooled to 50.0C . c)Find the mass of flesh that can be heated from 37.0C (normal body temperature) to 50.0C for the case considered in part A. (The average specific heat of flesh is 3500J/(kg)(K))

Explanation / Answer

a) 4.184*50*13= 2719.6 J b) 2260*13 + 2719.6 =32099.6 J c) 13*3.5*m =2719.6 m = 59.77 gms
