Becky is preparing tea. when the water for the tea boils, she pours it in a cup of cold milk. assuming that the system is closed and that thermal energy distribution is uniform when the hot water mixes with the cold milk, which of the following is true about the thermal energy of each of the liquids in the cup?

a. the thermal energy lost by the hot liquid will be equal to the thermal energy gained by the cold liquid.
b. the thermal energy lost by the hot liquid will be more than the thermal energy gained by the cold liquid.
c. the thermal energy lost by the hot liquid will be less than the thermal energy gained by the cold liquid.
d. a transfer of thermal energy will not occur between the liquids because the system is closed.

I think its C i did this before somwhere

Explanation:

Sorry if its not

explanation:

metals have excess of electrons whereas non-metals have deficiency of electrons. thus, in order to gain stability metals easily donate their electrons to the non-metals.

for example, electronic configuration of sodium is and electronic configuration of phosphorous is .

when a phosphorous atom and sodium atom combine together then sodium will donate is extra one electron to the phosphorous atom. as a result there will be formation of ionic bond between sodium and phosphorous.

the reaction will be as follows.

there, are three sodium sodium atoms and each of them will donate its one extra electron to phosphorous atom. thus, the sub-shell of phosphorous gets completely filled.  

thus, we can conclude that electrons are transferred from atoms of sodium to atoms of phosphorous. this transfer makes the sodium atoms donate one electron and the phosphorous atoms to gain one electron. as a result, the sodium and phosphorus atoms strongly attract each other.

put the answers   and i could answer.
