Question

if chilled coke and hot tea are kept together, tea cools down but coke gets warm. why

Answer 1

Answer:

Because the heat always flows from hotter body to colder body so the heat of tea escapes to the environment and the heat of environment is absorbed by the coke.

Explanation:

1) let us consider the case of tea first, the temperature of tea is greater than the temperatur of soorounding so the heat will flow from tea to sorrounding and as a result, the tea will loose heat and thus it's teperature will be decreased.

2) in the case of coke, the temperature of sorrounding is greater than that of coke so the heat will flow from sorrounding to coke and as a result, the coke will gain heat ans thus it's temperature will be increased.
