Eric is investigating what happens when heat is added or removed from an object. First he places a mug of hot chocolate in this hand and records the temperature of the hot chocolate and the surface of his hand every five minutes for a total of 15 minutes. He repeats this procedure when investigating heat flow with an ice cube. Use the diagram to answer the question below. A flowchart illustration with two forward (right direction) arrows and two backward (left direction) arrows. The phrase Mug of chocolate is followed by the forward arrow A that leads to the word Hand. The word Hand is followed by the forward arrow C that leads to the phrase Ice cube. The word Ice cube is preceded by the backward arrow D that leads to the word Hand. The word Hand is preceded by a backward arrow B that leads to the phrase Mug of hot chocolate. What could Eric conclude about what happens when heat is added or removed from an object after he completed his test with the mug of hot chocolate? A. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was absorbed by his hand. B. Arrow A shows the direction heat flowed because the temperature of his hand increased as heat was released from his hand. C. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by the mug. D. Arrow B shows the direction heat flowed because the temperature of the hot chocolate changed as heat was absorbed by his hand.
