A person touches a large chunk of ice with their hand and remarks, “This is making me cold.” Explain what this person is feeling. Is the ice transferring “cold” to the person? Is there a heat transfer occurring? Explain.

Cold temperature can't "flow" into a warmer object, in this case, the person's hand. The heat energy of the hand gets transferred to the colder object, the ice.

Answer:

In this case ice is not transferring cold to the person but person is transferring heat to the ice.

Step-by-step explanation:

A person touches a large chunk of ice with his hand at that time their is difference of temperature between person's hand and chunk of ice. Person's hand has higher temperature than chunk of ice.

We know that heat transfer from higher temperature to lower temperature. In this case also heat is transferred from person's hand to chunk of ice. In this way chunk of ice will start melting and man's hand start getting cold due to transfer of heat.

In this case ice is not transferring cold to the person but person is transferring heat to the ice.
