Most people have held ice cubes in their hands. What happens to an ice cube that we hold? What do we feel? After a while, our hands will feel cold as the ice cubes start to melt. This is due to the transfer of energy from our hands to the ice and the temperature difference between the two objects. The energy we are familiar with is called heat while temperature is the measure of a degree of heat or coldness of an object. In everyday life, heat or cold is commonly used to explain the degree of temperature of an object. An object that is said to be hot means it has a high temperature. Similarly, when an object is said to be cold, is means it is has a low temperature.

Why does heat move from our hands to ice cubes and not vice versa? This is due to the heat transfer from a high temperature (hand) to a low temperature object (ice cubes). As our hands come into contact with the cooler ice cubes, our hands will experience a temperature drop and begin to cool down. Ice cubes will experience an increase in temperature so that it melts. This process occurs until the temperature of both touching objects feel the same temperature. What if the displacement is from a low-temperature object to a high-temperature object? Can this process occur naturally? What is the relationship between temperature and heat? To find out the answer, let's do the following experiment:

**The water is not Hot and not Cold anymore** Heat moves from a high-temperature object to a low-temperature object. This means that heat can change the temperature of the object. To see how heat can affect the temperature of an object, we do the following experiment. https://steemitimages.com/DQmWP7iYxQ7Veqo6iWPdJCdgVCWsCHrVsect4zyqTNHUdpD/6.jpg[Image Source](https://www.emaze.com/@ATIIWWQT/science-investigation)

## What is needed? 1. Cold water 2. Hot water 3. 2 Glass containers 4. Thermometer

## What are we doing? 1. Insert hot water into the first glass 2. Insert cold water into the second glass 3. Measure the temperature of each glass with a thermometer 4. Insert hot water into cold water so it mixes 5. Measure the temperature of the mixture with a thermometer

## What happened? After hot water is mixed with cold water, the mixture of hot water and cold water has the same temperature. Why did that happen? Hot water has a higher temperature and the molecules move faster than cold water. Hot water gives a portion of its caloric energy to move cold water molecules so that it moves faster than before. Heat energy released by hot water causes the motion of hot water molecules to become slower. This causes the rate of molecular motion of the water to be the same so that the temperature of the two waters becomes the same.

## Conclusion From the above experiments it is concluded that heat energy can move fast due to temperature difference. Hot water will release its heat energy, while cold water has slower molecules and will receive the energy of the heat. Thus, heat can move naturally from high-temperature objects to low-temperature objects. However, heat can not migrate naturally from low-temperature objects to high-temperature objects without specific treatment and without the aid of tools.
