What else can I help you with?
Does an ice cube has energy?
Yes, an ice cube has energy in the form of thermal energy, which is the energy associated with the motion of its particles. The temperature of the ice cube is a reflection of its thermal energy content.
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 takes place as an ice cube cools a drink?
kinetic energy in the drink increasesA calorie of heat energy is transferred from the ice to the water of the drink. Because ice absorbs heat from the drink, cooling down its temp.Common mistake:People think that ice producess coldness, when all its doing to the drink is absorbing the heat, causing the ice cube to melt ;)You say that a calorie of heat energy is transferred from the ice to the water, but that is not entirely correct as a calorie is defined as the amount of heat that 1g of water releases when it cools by 1 degrees Celsius. What if i add a really small block of ice? Surely a calorie of heat will not be transferred from the ice to the water. Therefore it would be more correct to say that the total kinetic energy of the drink decreases.
Heat is transferred from your body into an ice cube by?
conduction, as thermal energy flows from higher temperature to lower temperature through direct contact between two objects.
How does thermal energy transfer melt an ice cube at room temperature?
Thermal energy from the surrounding room causes the ice cube to absorb heat, causing its temperature to increase. Once the ice cube reaches its melting point, the thermal energy break the bonds between the water molecules in the ice, turning it into liquid water.

What does ths question mean which does the thermal energy move when you place an ice cube on a table?
When you place an ice cube on a table, the thermal energy will move from the ice cube to the table. Heat will transfer from the ice cube, which is at a lower temperature, to the table, which is at a higher temperature, until both reach thermal equilibrium.
What causes the sensation of cold when you touch a ice cube?
When you touch an ice cube, heat is transferred from your skin to the ice cube. This heat transfer lowers the temperature of your skin, triggering nerve endings that sense cold temperature. This sensation of cold is a signal sent to your brain that tells you the ice cube is colder than your skin.
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.
What occurs when is transferred from one object to another?
Well, it's exactly that- energy is being either radiated, convected, or conducted through, to, or from an object. Energy needs a medium to travel through- and it's travelling because it needs to reach what every little atom in the world needs- equillibrium. For example, the reason things feel hot and cold is because energy is being transfered from the- let's say, an ice cube- to your hand. The cold energy is trying to mix with the hot energy, and create what we bluntly call room temperature (one side effect, though, is a melted ice-cube.) xD
What is taking place at the molecular level when you place an ice cube into hot soup?
Heat is transferred from the hot molecules to the cold ones. That means that faster molecules collide with the ice molecules; the ice molecules gain enough energy to escape from the other ice molecules (to break the bonds that kept them together).
Boiling water transfers energy to an ice cube this is an example of what?
This is an example of heat transfer through conduction. The hot water molecules transfer thermal energy to the colder ice cube molecules, causing them to gain energy and melt.
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.
