Question

On a hot summer day, you and your friends decide to have a picnic at the park. To keep your food fresh you pack your lunch in a large insulated cooler. Unfortunately, you have no extra ice, and discover that your reusable freezer pack is missing. Your friends suggest various substitute objects to place in the cooler o keep the food cool an eight-kilogram lump of aluminum which was found in the back of the refrigerator four kilograms of fruit juice that's been in the fridge for the last three days .a two-kilogram bag of light and airy angel food cake, which was stored in the fridge overnight Because of your knowledge of physics, your friends leave the final decision to you Which object would be most effective in helping to maintain a low temperature in the cooler, and why? should be put in the cooler, because O it is the coldest object angel food cake lump of aluminum fruit juice The O O O O O it is the best thermal conductor it is the best thermal insulator it has the lowest heat capacity it has the greatest heat capacity O O O O absorb the most heat for each degree it increases in temperature best prevent heat from entering the cooler absorb the least heat for each degree it increases in temperature best conduct heat away from the other objects in the cooler and will therefore

Answer:

The Fruit juice should be put in the cooler, because it has the greatest heat capacity and will therefore, absorb the most heat for each degree it increases in temperature.

Explanation:

in order to understand the answer above we need to know what specific heat capacity is

       Specific heat capacity  can be defined as the amount of heat required to raise the temperature of a unit mass of a substance by one degree  

     Looking at the specific heat of each substance suggested we see that the fruit juice has a higher specific heat capacity than others this is because it contains a higher amount of water , generally liquid states of substances have a higher specific heat capacity than other states. The specific heat capacity of fruit juice being the highest among the suggested substances means that it can absorb  more heat for each degree temperature of refrigerator.
