Answer:
D) Water temperature decreases; copper temperature increases
Explanation:
The temperature is a way of describing how much heat something has. Because the temperatures of the two substances are not the same, the heat is going to want to travel to the substance with less heat. Therefore, since the copper has less heat than the water, the heat will be transferred to the copper. Remember that this heat is now leaving the water. This increases the temperature of the copper and decreases the temperature of the water.
El vidrio no templado contiene burbujas de aire microscópicas que se expanden y contraen a medida que el vidrio se calienta y enfría, especialmente a temperaturas extremas como durante el enlatado y la congelación. Cuando esas pequeñas burbujas de aire se expanden, hacen que el vidrio se rompa o incluso explote. Espero que esto haya ayudado, por favor, dé cinco estrellas y mentalmente.
