Aperson packs two identical coolers for a picnic, placing twenty-four 12-ounce soft drinks and 5 pounds of ice in each. however, the drinks put into cooler a were refrigerated for several hours before they were packed in the cooler, while the drinks put into cooler b were at room temperature. when the picnickers 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.\

The rate of heat transfer in cooler A is lower than the rate of heat transfer in cooler B and more heat energy is being transferred in cooler B than in cooler A.

Explanation:

A person packs two identical coolers for a picnic, placing twenty-four 12-ounce soft drinks and 5 pounds of ice in each. However, the drinks put into cooler A were refrigerated for several hours before they were packed in the cooler, while the drinks put into cooler B were at room temperature.

Therefore, the drinks in cooler A are at lower temperatures than those in cooler B because the drinks in cooler A have been refrigerated for several hours.

Generally when there is temperature gradient in a system, heat energy will flow from the body at high temperature to the body at low temperature until thermal equilibrium is reached.

The rate of heat transfer in cooler A is lower than the rate of heat transfer in cooler B and more heat energy is being transferred in cooler B than in cooler A. As a result, majority of the ice in cooler B has melted while there are still more ice in cooler A.  

c is having 4 valence electrons and is bonded to three hydrogens and one sulphur atom, therefore, the number of bond pair is equal to four. as all the valence electrons are used in forming the bonds so, there is no lone pair left on carbon.

s is having 6 valence electrons and is bonded to one other sulfur atom and one carbon atom, therefore, the number of bond pair is equal to 2. as only two valence electrons are used in forming the bonds so, four electrons are left. therefore, two lone pairs are present on s.
