At what temperature will a block of metal feel neither hot nor cool when you touch it?
The principle behind this is called heat transfer. Heat transfer says that heat (or thermal energy) always transfers from high energy objects(hot) to a low energy objects(cold). If you touch a stove, what you feel is a large amount of thermal energy being transferred into you through your contact with the stove. The hotter the object, the more thermal energy will be transferred into you. The skin can only handle so much thermal energy, so eventually you'll get burned. On the opposite spectrum, if you touch an ice cube, you feel a cold sensation because thermal energy is transferred from your hand and into the ice cube. So what does this all mean? There is no transfer of cold, just transfer of heat. Heat gets transferred when the temperature of two objects are different and the two objects come into contact. Heat always transfers from higher temp to a colder temp. Your question is asking, how will I not feel hot or cold when touching a block of metal. That would only occur if the metal was the same temperature as you. In reality though, the entire process is very complex. Thermal energy may not be uniformly distributed in the object. Our bodies are not a constant temperature everywhere, it fluctuates from area to area. Our hands also have small sensors that get activated if heat gets transferred away and then there are other sensors that get activated if heat gets transferred into you.
Why will heat not flow from an ice cube to a hot drink?
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.
What provides the energy in a fridge to transfer?
an extremely large ice cube made of di-nitrogen polyeurathenimin in the back storage.
Which form of energy causes an ice cube to melt?
whatever's around it, assuming it's in surroundings warmer than 0 Celsius. Everything has heat energy, unless it's at 0 degree kelvin (-273 Celsius), so the warmer surroundings transfer some of this warmth to the colder ice
What is a melting ice cube's kinetic energy?
Erm, it depends how fast it is moving! Kinetic energy is energy due to motion. If the ice cube is stationary, then it has no kinetic energy.
How do you perform energy transfers?
A simple way to illustrate energy transfer is to put an ice cube in a glass of water. The heat energy from the water will transfer to the ice cube until thermal equilibrium.

Which energy transfer occurs when ice cubes are placed in water that has a temperature of 45C?
it gained no energy. it melted. therefore is no longer an ice cube, & something that doesnt exist has no engery.
How does ice cool something?
Okay, let's say you put ice next to some coffee. Thermal energy travels from the coffee into the ice. So when the thermal energy store in the coffee decreases the temperature decreases and the ice cube increases and melts. I hope I helped
Why does ice cube melt when it is heated?
in the solid state of water {ice} the molecules are well orderly arranged .as thermal energy decreases the freedom for movement of molecules are affected. Thus when temperature increases the thermal energy of molecules increasesand they began to move in random motion. that is the melting of ice.
What causes the sensation of cold when you touch a ice cube?
loss of thermal energy from your finger.
Where does thermal energy move to when you put an ice cube to hot soup?
Heat moves from the water that has higher temperature towards the ice cubes. This transfer of heat melts the ice cubes. Remember that heat travels from higher temperature body towards the one with the lower temperature. So thermal energy flows from the water on the glass towards the ice cubes.
What is the change in which energy is given off?
When we consider changes involving the release of energy, one that quickly might come to mind is cooling. If the temperature of a material goes down, it is releasing thermal energy to become cooler. Consider an ice cube tray in a freezer. Liquid water fills the tray, and after a period of time during which the water gives off thermal energy (heat), it undergoes a phase transition and becomes ice.
Why will heat not flow from an ice cube to a hot drink?
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.
What does ths question mean which does the thermal energy move when you place an ice cube on a table?
thermal energy always travels from the warmer object to the cooler object in order to reach equilibrium. The energy moves from the table to icecube. Unles your table is VERY cold.
Is melting an ice cube an example of endothermic processes?
Yes, the ice cube must absorb thermal energy from its surroundings to undergo the phase change, so the process is in fact endothermic.
What are three mechanisms of energy transfer?
There are many mechanisms of energy transfer, assuming you simply mean transferring energy to or through something. Here are a few:Radiation as electromagnetic radiation (e.g. UV light from the sun hitting your skin and causing a sunburn transfers electromagnetic energy from the sun to your skin)Physical collisions (e.g. a car hitting a tree and causing it to break transfers kinetic energy from the car to the tree)Thermal conduction (e.g. heat moving from your warm hand to a cold ice cube transfers molecular vibrational energy from your hand to the ice cube)Electrical conduction (e.g. current in a wire transfers electrical energy through a circuit)Thermal convection (e.g. a warm air current rises over a cold one due to its lower density, transferring heat energy from one part of the atmosphere to another)
