heat will flow from the warmer item (with more heat energy) to the cooler item (with less heat energy) until both have the same temperature.

Given two objects with different temperatures, heat will flow towards the object of lower temperature. Thus, heat flows from "hot" to "cold".

No. If the two objects are at temperature equilibrium, there is no heat difference between them and thus no net flow.

ESD stands for electrostatic discharge, which is a sudden flow of electricity between two charged objects. This is due to contact, an electrical short, or dielectric breakdown.

Technically the answer to your question is no. Heat does indeed flow between objects, but cold does not because it doesn't really physically exist. "Cold" is just a lower level of heat.

When both temperatures are the same, heat does NOT flow between objects.

I am not sure how the two objects of equal resistance are supposed to be connected. But for a current to flow, for example across a resistor, there must be a voltage difference between the terminals of this resistor.

Heat will flow naturally from hotter objects to colder objects. To flow the other way, from colder objects to hotter objects, requires energy to be used.

A flow of charge is called a current. It is measured in coulombs per second per amperes.

electricity can flow between two objects! if you are using a light bulb and a buzzer the energy from the light bulb and the lamp charges the buzzer. therefore having the buzzer make a very loud buzzing noise

When they are in thermal contact and their temperatures are the same there is no NET flow of energy. If the objects are both thermally insulated there will be no flow of energy at all.

Between two rigid objects:Increase the surface area that is in contact between the two objectsIncrease the roughness of the surfaces in contactIncrease the relative speed of the two objectsIncrease the force that pushes the two objects together.Between a rigid object and a fluid:Change the shape and/or orientation of the object so that a greater surface area encounters the fluid streamIncrease the relative speed of the object through the fluidIncrease the viscosity of the fluidIncrease the roughness on the surface of the object (leads to more turbulent flow of the fluid)

The mechanisms to transfer heat are conduction, convection, and radiation. Heat will naturally flow from hotter to colder objects.

The continental divide determines which direction the rivers flow. Water seeks to find its way to the sea by the easiest route.

No. A flow of charges is called a current. It is measures in coulombs per second or amperes.

In this case, no heat will flow between the objects. At least, there will be no "net" heat flow. The objects are said to be in thermal equilibrium, so that any heat exchanged by their molecules is balanced and there is no net change in temperature.

Temperature is a physical property and it determines how hot or cold an object is. Heat flow is always from hot to cold.

In that case, heat will flow from the hotter to the colder object. This will continue until both are at the same temperature.

Heat energy travels from a hotter object to a cooler/colder object until both objects reach the same temperature.

Heat is the flow of thermal energy from one object to another. Heat always moves from warm objects to cool objects, not cool objects to warm objects.
