Question

Ice at 0 degrees Celcius is more effective in cooling as compared to water at 0 degrees Celcius. Why?

Answer 1

• Cooling refers to the loss of heat from the body.
  
• In the case of Ice at $0^{o}C$, ice will take latent heat from the system to convert its state from solid to liquid and then water at high temperature.
• But in the case of water at $0^{o}C$, water does not require any latent heat.
• Hence, Ice at $0^{o}C$ is more effective in cooling as compared to water at $0^{o}C$.
