A cup of coffee is so hot that it cannot be drunk. As a result, an ice cube is put into the coffee. What direction is the energy moving? When would the energy flow stop?

The energy will be flowing from hot coffee to ice cube. The energy flow will stop when both temperatures of coffee and ice cube will become equal.

Explanation:

The second law of thermodynamics deals with the direction in which spontaneous processes go. Many processes run spontaneously in one direction, that is, they are irreversible under certain conditions. Although irreversibility is seen in everyday life, for example, a broken glass does not return to its original state, complete irreversibility is a statistical statement that cannot be seen during the life of the universe. More specifically, an irreversible process is a process that depends on the route. If the process can only go in one direction, the reverse path is fundamentally different and the process can't be reversible. For example, heat always involves the transfer of energy from a higher temperature to a lower temperature. A cold object that comes in contact with a hot object never cools, transfers heat to the hot object, and heats it up.

i think its 100

i hope this !

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.
