How many minimum ice cubes each of mass 10 gm and temperature should be added to a glass of water containing 100 gm water at 20°C to bring the temperature of mixture below 5°C. The heat capacity of glass is . Neglect heat loses.
Options:
Answer:
B
Solution:
Cooling water plus glass from 20°C to 5°C releases (100+50)×15=2250 cal.
Each 10 g ice cube needs 800+50=850 cal to melt and warm to 5°C. Three cubes are insufficient and four are enough.
