Matching words. I need help with this.
Complete the sentences describing the steps needed to calculate the energy change associated with the conversion of 423g of water ice at ?10 ?C to steam at 125 ?C.
1) Calculate the energy required to change the temperature from -10C to ____.
2) Calculate the energy associated with the phase change from _____ to _____.
3) Calculate the energy required to change the temperature from ____ to _____.
4) Calculate the energy asociated with the phase change from____ to _____.
5) Calculate the energy required to change the temperature from_____ to 125C.
Liquid water
ice
0C
125C
100C
steam
Explanation / Answer
Calculate the energy required to change the temperature from -10C to 0C. (note water begins to freeze at 0C)
Calculate the energy associated with the phase change from ice to liquid water.
Calculate the energy required to change the temperature from 0C to 100C. (note water begins to boil at 100C)
Calculate the energy asociated with the phase change from liquid water to steam.
Calculate the energy required to change the temperature from 100C to 125C. (note above 100C water vapor, steam, will be produced)
