Two identical coolers are packed for a camping. Each cooler is packed with ten-one liter softdrinks and 1.5 kg of ice. The softdrinks that were packed in cooler A were first put inside the refrigerator for 8 hours, while the softdrinks that were packed in cooler B were only kept at room temperature for 8 hours also. When the campers opened the coolers after 4 hours later, most of the ice in cooler A is still ice, while almost all of the ice in cooler B have already melted. Explain what happened with the two coolers.

Explanation:

The drinks that were put into cooler A have lower temperatures than the drinks that were put into cooler B.

As heat flows from high temperature to low temperature until it reaches equilibrium, more heat flows from the drinks to ice in cooler B than the heat flows from the drinks to ice in cooler A.

Thus, most of the ice in cooler B is melted as heat is transferred to the ice that results in its phase change.

the law of conservation of mass states that in a chemical reaction, the total mass of reactants is equal to the total mass of products. because atoms are only rearranged in a chemical reaction, there must be the same number of sodium atoms and chlorine atoms in both the reactants and products
