RD Exam Prep: Domain 1 Topic A Questions and Answers 100% Pass Water - Answer- Boiling point: 212 degrees F at sea level. Drops 1 degree F for every 500 foot increase in altitude. Freezing point: 32 degrees F. The addition of salt or sugar lowers the freezing point of water. Salt lowers the freezing point 2x as much as sugar. Water Activity (WA): Foods with higher WA levels are more likely to spoil. Fresh foods like milk, meats, and veggies have a WA level of 0.95-1.0 Water makes these c...
