use the particle theory of matter to explain how a solid can melf if sufficiently heated
According to the particle theory of matter, all matter is made up of tiny particles that are constantly moving. In a solid, these particles are closely packed together and have very little energy. When heat is added to a solid, the particles begin to vibrate more rapidly, and this causes them to gain kinetic energy.
As the kinetic energy of the particles increases, they begin to overcome the attractive forces that hold them in a fixed position. The particles begin to move further apart and the solid starts to expand. Eventually, if the solid is heated enough, the particles will have enough kinetic energy to break free from their positions and move around freely. At this point, the solid has melted and become a liquid.
In summary, the addition of heat to a solid causes the particles to gain kinetic energy, they begin to move more rapidly, break the attractive forces holding them in place and start to move apart expanding the solid. If they acquire enough energy to break completely free, the solid melts and becomes a liquid.
The particle theory of matter can help us understand how a solid can melt when it is heated enough. According to this theory, matter is made up of tiny particles, such as atoms or molecules, that are constantly in motion.
In a solid, these particles are tightly packed together and vibrate in fixed positions. The attractive forces between the particles are strong, which gives solids a definite shape and volume.
When heat is applied to a solid, it increases the energy of the particles. This added energy causes the particles to vibrate more vigorously. As the temperature of the solid continues to rise, the particles gain even more energy and their vibrating motion becomes more intense.
Eventually, as the solid is heated sufficiently, the energy of the particles overcomes the attractive forces holding them in fixed positions. At this point, the particles start to break away from their neighbors and move more freely. This process is known as melting.
During melting, the solid undergoes a phase change and transforms into a liquid. The particles now have enough energy to slide past each other, allowing the solid to lose its fixed shape and take on the shape of its container. However, the liquid still has particles that are close together, as the attractive forces between them are still present.
In summary, the particle theory of matter explains that when a solid is heated, the added energy causes the particles to vibrate more intensely. As the temperature further increases, the particles gain enough energy to break away from their fixed positions, resulting in the melting of the solid and the formation of a liquid.
