    The ice is cooler than the table.

    Explanation:

    The difference in temperature is a necessary condition for the transfer of heat between two bodies.

    Here if the heat is being transferred from the table to an ice block this means that the temperature of the table is greater than the ice which drives the heat energy from the table to the ice block and the heat will continue to flow until they both attain a common temperature.

    However,

    we can tell nothing about the friction between the two bodies from the given information. the ice may or may not be changing its phase based upon the fact that the whole process might be occurring below zero degree Celsius such that the ice is having more cooler temperature than table.
