Cooling Effect of Ice vs. Water at 273 Kelvin

The video explains why ice at 273 Kelvin is more effective in cooling than water at the same temperature. Ice absorbs additional heat energy, known as latent heat, to overcome fusion and become water, enhancing its cooling effect. In contrast, water at the same temperature does not absorb this extra heat, making ice a more efficient cooling agent.

Why is ice at 273 Kelvin more effective in cooling than water at the same temperature?

• Ice absorbs latent heat to become water.

• Water releases heat to become ice.

• Water has a higher specific heat capacity.

• Ice has a lower temperature than water.

What does ice at 273 Kelvin absorb from the medium to become water?

• Radiant heat

• Latent heat

• Convection heat

• Sensible heat

What is the process called when ice absorbs heat to become water?

• Condensation

• Sublimation

• Fusion

• Evaporation

Why does water at 273 Kelvin not have the same cooling effect as ice?

• Water has a higher temperature than ice.

• Water does not absorb extra heat from the medium.

• Water releases latent heat to the medium.

• Water absorbs more heat from the medium.

What is the main reason for the greater cooling effect of ice compared to water at the same temperature?

• Ice has a lower specific heat capacity.

• Ice absorbs latent heat during fusion.

• Water has a higher density than ice.

• Water releases heat during condensation.
