Cambios de estado

The video tutorial explains the states of matter: solid, liquid, and gas. It describes how matter can change from one state to another through heating or cooling. When solids are heated, they melt into liquids, and when liquids are heated, they evaporate into gases. The video also covers the process of condensation and how even cold liquids can evaporate by absorbing heat from the surrounding air. Practical advice is given on how to prevent a snowman from melting by protecting it from the sun.
