Answer:
No. A
Explanation:
cause due to the friction between both molecules heat is produced rapidly.
Well , when liquid water is kept at a temperature below it's freezing point it turns into ice. As the temperature of surrounding is below freezing point , it freezes. Hence the liquid water freezing at a temperature below its freezing point is a spontaneous process.
1. Particles in gas can MOVE AROUND QUICKLY
2. When you remove energy from particles they move SLOWER and the matter CONTRASTS
Answer:
Two characteristics that make water a good choice for the recrystallization solvent for benzoic acid are
- Low solubility for benzoic acid at room temperature
- Less expensive
Explanation:
Characteristics of a Good Recrystallization Solvent:
- Cheap.
- High volatility.
- No reaction with substrate to be made pure.
- Insoluble impurities should not be dissolced by the olvent at all temperatures.
- At room temperature the solvent should have high solubility for soluble impurities well
- At room temperature the substance to be purified should be insoluble in the solvent.
As such water has both low solubility for benzoic acid at room temperature and water is cheap or readily available
