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

    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.

    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.
