Heat transfer occurs from hot to cold. Heat always moves from a higher temperature to a lower temperature.
Heat transfer occurred from your finger to the cold water, as heat moves from a higher temperature region (your finger) to a lower temperature region (the water) in an attempt to reach thermal equilibrium.
The mode of heat transfer is conduction, where heat transmits from the warmer hand to the colder water molecules.
Heat transfer occurs when a substance transitions from a hot temperature to a cold temperature through the process of conduction, convection, or radiation. Conduction is the transfer of heat through direct contact between particles, convection is the transfer of heat through the movement of fluids, and radiation is the transfer of heat through electromagnetic waves.
Heat transfer occurs from areas of higher temperature to areas of lower temperature in the direction of decreasing thermal energy. Heat transfer can occur through conduction, convection, or radiation depending on the medium through which it is transferring.
Heat transfer can be unidirectional (one-way transfer of heat from one object to another), such as in conduction or convection, or bidirectional (two-way transfer of heat between two objects), such as in radiation. The direction of heat transfer depends on the temperature difference between the objects involved and the properties of the materials.
When you dip your hand in cold water you feel it cold. Can you name the mode of heat transfer and its direction?
This type of heat transfer is called conduction. The transfer is from the warm hand to cool water.

No, according to the second law of thermodynamics, heat transfer occurs naturally from a hot reservoir to a cold reservoir. It is not possible to transfer heat in the opposite direction without external work being done.
hot to cold is heat transfer
No, heat transfer occurs due to a temperature difference between two substances. If both substances are at the same temperature, there is no temperature gradient to drive heat transfer, so no heat transfer will occur.
Heat flows from hot to cold.
Heat moves from areas of high temperature to areas of low temperature, until an equilibrium is reached. This movement is known as heat transfer and can occur through conduction, convection, or radiation.
