According to the Kinetic Molecular Theory, gases are composed of tiny particles called molecules that are in constant random motion. This motion is influenced by their kinetic energy. When a gas is confined to a specific space, the molecules collide with each other and the walls of the container, creating pressure.
When a gas diffuses, it means that the gas molecules spread out and mix with other gases or move to areas of lower concentration. This rapid diffusion can be explained by three key factors:
1. Continuous motion: Gas molecules are in constant motion due to their kinetic energy. This random motion causes them to collide with each other and move in different directions.
2. Negligible intermolecular forces: Gases have weak intermolecular forces compared to liquids and solids. The molecules are far apart, and the attractive forces between them are relatively weak. As a result, they are free to move independently.
3. Empty space: Gases occupy a larger volume compared to their actual molecular size. The majority of the space within a gas is empty, allowing the molecules to move easily and quickly.
Due to these factors, gas molecules can rapidly diffuse because they are constantly moving, experience weak intermolecular forces, and have ample space to spread out and mix with other gases.

What is the Difference between tcs and non tcs foods
Answer:
Tcs foods are foods that pose a greater risk of causing foodborne illness if not prepared.
Non Tcs foods on the other hand, are foods that are less likely to support the growth of bacteria and have a lower risk of causing foodborne illness.

Based on the given bright-line spectra and the observed wavelengths in the mixture's spectrum, the elements G and J are the ones present in the mixture.
From the given bright-line spectra and the spectrum of the mixture, we can determine the elements present in the mixture by comparing the specific wavelengths observed. Examining the bright-line spectra, we can identify that G has a distinct wavelength at 650 nm, J at 600 nm, L at 550 nm, and M at 500 nm.
Looking at the spectrum of the mixture, we can observe two prominent wavelengths, 650 nm and 600 nm. These correspond to the wavelengths of G and J, respectively. Since the spectrum of the mixture does not exhibit the wavelengths specific to L (550 nm) or M (500 nm), we can conclude that only G and J are present in the mixture.
Therefore, based on the given bright-line spectra and the observed wavelengths in the mixture's spectrum, the elements G and J are the ones present in the mixture.
This analysis relies on the principle that each element has characteristic wavelengths at which they emit light. By comparing the observed wavelengths in the mixture's spectrum with those of the individual elements, we can determine the elements present in the mixture.
