Heat lost or gained is directly proportional to the change in temperature , ΔT:
Melting → absorbs heat
In each cooler:
Melting temperature of ice = 0°C
Room temperature = ~25°C
We pack two identical coolers for a picnic, placing 24 12-ounce soft drinks and five pounds of ice in each. However, the drinks that we put into cooler A were refrigerated for several hours before they were packed in the cooler, while the drinks that we put into cooler B were at room temperature. When we open the two coolers three hours later, most of the ice in cooler A is still present, while nearly all of the ice in cooler B has melted.
Explain this difference.
