Answer:
Unlike solid and liquid state, molecules in gaseous state show random motion. That is the reason, gases take the shape of container and spread quickly in space. The random motion of molecules in the gaseous state is due to high kinetic energy in molecules. They have weak intermolecular interactions between them. The intermolecular space between gaseous molecules is very large. They can show all the three types of molecular motion, vibrational, rotational and translational motion. In vibrational motion, molecules move back and forth whereas in rotational motion the molecule rotates in space. In translational motion molecules move in certain directions. Molecules of solid-state are capable of vibrational motion due to strong intermolecular forces. Therefore, they show least random molecular motions. Like solids, liquids are capable of vibrational motion but at the same time they can also show rotational and translational motions due to weak intermolecular forces between molecules. Hence, liquids can show random molecular motions but less random compared to gas molecules. So we can say that random motion is related to temperatures, intermolecular forces of attractions, the kinetic energy of molecules and heat transfer.

Non-durable goods are those good used by ordinary people are most affected by scarcity.
Explanation:
Non durable goods are those goods that is limited in nature that is it will last for lesser than three years and non durable goods are needed for survival of human beings. The necessities needed for survival is food and clothing. Two types of non durable goods are customer goods and the capital goods.
In terms of economics scarcity refers to lack of different types of capital. Due to unlimited wants and needs of people scarcity of capital goods can occur. If the consumer always have fascination for new things the resources become limited.
The Andes in western South America is an example of a landform that arises from the movement of the tectonic plates.
The Andes mountain range is the mountain range that runs along South America's whole Pacific Ocean coast in the west. It is the world's longest continental mountain range, stretching 8500 km.
It was created by the convergence of the South American and Nazca plates towards the end of the Late Cretaceous, at the end of the Mesozoic era. In the relief configuration, seismic movements and consequent volcanic activity have been more significant than external erosive processes.
There are high mountain ranges in the existing morphology, as well as broad high plateaus, deep longitudinal valleys, and vast mountain ranges. Except for in the Argentine-Chilean Andes, transversal valleys are uncommon.
