Have you ever walked on hot sand? If so, you may have run towards the water. The water is cooler than the sand, so it will cool off your hot feet. Why is the sand so hot, but the water much cooler? _______________________________.
The sand is hot because it absorbs and retains heat from the sun's rays. Sand particles are made of minerals that have the ability to trap heat energy. As a result, when the sun shines on the sand, it gets heated up quickly and can become quite hot.
On the other hand, water has a high specific heat capacity, which means it requires a lot of energy to heat up. This allows the water to resist temperature changes and remain cooler for longer periods. Additionally, water has excellent thermal conductivity, meaning it can effectively transfer heat away from objects in contact with it. So when you step into the water, it absorbs the heat from your feet, rapidly cooling them down and making it feel cooler than the hot sand.
