It does contain heat energy. Usually not enough to transfer to its surroundings but a lot more than liquid nitrogen, for example.
Any object that has a temperature above absolute zero - in other words, any object - contains heat energy.
Heat energy transfers from your hand to the ice. This is because heat always passes from the cooler object to the hotter object. The ice gains heat energy, so it heats up.
Despite what it may feel like when your spouse puts his/her feet into your back in bed at night, human skin is warmer than ice. Because of the difference in temperature, thermal energy is transferred as heat from the warmer object (your hand) to the cooler object (the ice) via conduction.
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 = molecular motion =energy If you apply energy to say, a nail, the particles that the nail consists of will start moving faster, and the nail will heat up. The same goes the other way around: If you put the hot nail on a block of ice, the ice will cool the nail down. The particles will start moving slower, and the overall energy held by the nail is lessened.
give off heat
It depends upon the condition of the ice and the environment it is in. For example, a block of ice in room temperature does not give off energy - to the contrary, it absorbs energy as it melts. . But a block of ice at -5oC that is set in freezer that is -20oC will give off its thermal energy until the block of ice's temperature falls to the freezer's temperature.
Heat energy transfers from your hand to the ice. This is because heat always passes from the cooler object to the hotter object. The ice gains heat energy, so it heats up.
The heat will flow from the boiling water to the block of ice.
Heat because Ice and water would thaw out and begin to heat up
Despite what it may feel like when your spouse puts his/her feet into your back in bed at night, human skin is warmer than ice. Because of the difference in temperature, thermal energy is transferred as heat from the warmer object (your hand) to the cooler object (the ice) via conduction.
Heat energy would flow from the hand to the ice, unless the hand is colder than the ice, in which case the heat energy would flow from the ice to the hand.
The answer depends on howlarge a block of ice it is.

ya when ice convert to water then it flows.......
Although ice possesses certain amount of heat energy, it is less than that possessed by a person. When a person touches ice, the heat energy from his/her body is transferred to the ice to reach equilibrium (equal amount of heat in the person's body and in the ice). Since heat is not being received that is why it is not felt either. Since heat energy is being given away, a person feels cold.
Then part of ice melt, and table become wet.
