The puddle under an ice cube is as cold as the ice cube because the ice cube is melting and releasing its cold temperature into the water, keeping the surrounding water at a low temperature. Heat transfer occurs from the ice cube to the water until thermal equilibrium is reached, resulting in a cold puddle.
Yes, the process of a puddle freezing into ice on a cold night is a physical change. This is because the state of matter is changing from a liquid (water) to a solid (ice) without altering the chemical composition of the substance.
An ice cube is typically around 32 degrees Fahrenheit (0 degrees Celsius). The temperature of an ice cube is influenced by factors such as the temperature of the surrounding environment, the material the ice cube is made of, and the amount of time it has been frozen.
The answer depends on where the ice cube is in relation to the stove: it could be conduction, convection or radiation.
heat is transferred from your skin to the ice cube due to the difference in temperature between them. This transfer of heat causes the ice cube to melt and the sensation of coldness is felt as the heat is removed from your skin.
There is no ice cube that never melts under normal conditions. However, there are materials like Pykrete, which is a mixture of sawdust and ice, that melt at a slower rate compared to regular ice cubes.
The answer is that the system is in 'equilibrium'. More exactly thermal equilibrium. Ice and Water can both form at 0C and 1 ATM. When two things are touching, they are at equilibrium with each other. Since the ice cube has had enough time to melt, it has had enough time to reach equilibrium with the water and is at 0C.

It is a physical change.
An ice cube is a frozen diamond, preserving its coolness until it melts away.
MAYBE
Unless the dry ice is under pressure, it will "sublime" and change from a solid to a gas. Therefore, there will be no "puddle".

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.
Cold water.
The juice is warmer than the cold ice cube, so the heat causes the ice to melt.
