In an antifreeze formulation, 35% (v/v) ethylene glycol in water lowers the freezing point of water to about:
A255 K
B273 K
C268 K
D240 K
Answer & Solution
Correct answer: A. 255 K
Per NCERT: a 35% (v/v) ethylene-glycol antifreeze depresses the freezing point of water to **255.4 K (−17.6°C)**. Used as engine coolant in cars.
