Question

maria takes some cookies out of the freezer and leaves them on the table to defrost (warm up). a half-hour later she returns, and the cookies are at room temperature. which of the following G/R energy diagrams most accurately describes the chain of interactions involving the cookies, table and sureounds (mainly the air) during the time that the cookies are defrosting (warming up)

Decrease in thermal energy Heat interactions Surroundings Energy Cookies Table Energy Heat interactions Decrease in thermal Increase in thermal onerov anaro

Answer 1

Solution:

Ans(A)

Reason: When the cookies are warming up, the heat energy flows from the table and surroundings into the cookies. This happens because the cookies are at a lower temperature than the table or surroundings. Heat flows from body having higher temperature to body having lower temperature. The flow of heat energy continues till both are at same temperature. Due to this thee thermal energy of table and surroundings decrease and thermal energy of cookies increase.
