Web1M glucose solution has the highest freezing point because it has lower ΔT f(ΔT f=T f∘+ΔT f) since it does not undergo dissociation to increase the number of particles. Solve any question of Solutions with:-. Patterns of problems. WebFreezing or frost occurs when the air temperature falls below the freezing point of water (0 °C, 32 °F, 273 K).This is usually measured at the height of 1.2 metres above the ground …
Web4 de abr. de 2024 · Hence, glucose will have the highest freezing point. Therefore, the correct option is: (i) $ 1M $ glucose. Note: We should remember that the van’t hoff factor determines the degree of dissociation, association of a non-volatile solute when it is dissolved in a solvent. WebConsequently, nitrogen freezes at a much lower temperature than water. It even liquifies at a much lower temperature than water: -195.8 °Celsius. It freezes solid at -209.86 °C. Water in comparison, freezes at zero degrees Celsius. We use liquified nitrogen here at the Physics van for lots of great demonstrations because it is so very cold.
