A patient arrives in the emergency room with a burn caused by steam. Calculate the heat that is released when 17.4 g of steam at 100. ∘C hits the skin, condenses, and cools to body temperature of 37.0 ∘C. (For water, 540 cal (2260 J) is needed to convert 1 g of water to vapor at 100 ∘C.)

Using the values for the heat of fusion, specific heat of water, and/or heat of vaporization, calculate the amount of heat energy in each of the following:

A. joules needed to melt 90.0 g of ice at 0 ∘C and to warm the liquid to 85.0

B. kilocalories released when 30.0 g of steam condenses at 100 ∘C and the liquid cools to 0 ∘C

C. kilojoules needed to melt 26.0 g of ice at 0 ∘C, warm the liquid to 100 ∘Cand change it to steam at 100 ∘C

∘C

Calculate the change in heatwhen 12.60g of water vapor (steam) at 100.0C condenses to liquidwater and then cools to 22.50C. For water:

Sice=2.09J/g*C

DeltaHfus=6.01kJ/mol

Swater=4.184J/g*C

DeltaHvap=40.79kJ/mol

Ssteam=1.99J/g*C


Every time i work it out i getit wrong, I keep getting 34721 Joules as the answer, Thankyou
