Question

which is more effective in cooling option a - Ice at 0 degree celsius option b - water at 0 degree celsius option c - water at 100 degree celsius option d - ice at 100 degree celsius

Answer 1

Answer:

Ice at 0 degree is more effective.

Explanation:

because ice needs additional energy to convert itself to water at zero degree C . Thus it absorbs more heat from the liquid system making the liquid system cooler so ice at 0 degree C is cooler than water at 0 degree C.

Answer 2

Same temperature because of extra latent heat and therefore when used for cooling,Ice can absorb more heat than water at same temperature and have more effective cooling. ... It has transformed from solid ice to liquid water by consuming Latent heat which can't be sensed by thermometer & that's why it shows 0°C.
