The kinetic molecular theory is a collection of several rules that describe the behavior of gases. The nature of gas molecules was examined by scientists, such as Robert Boyle and Jacques Charles, who outlined their observations in several laws that eventually became the Kinetic Molecular Theory. Volume, temperature and pressure are all taken into account when observing and understanding the behavior of gases.Know More
The kinetic molecular theory is composed of five postulates, one of which states that gas particles are in constant random motion and, according to Newton’s laws, remain in random motion unless acted upon by an outside force. Another rule is that the volume gas molecules occupy is negligible when compared to the volume of the container in which they exist. A third rule posits that when gas molecules collide, there is no loss or gain of energy. Another rule states that there is no notable force of attraction between gas particles. The last rule explains that kinetic energy can be determined by using the equation 3kT/2, in which k is a constant and T is the temperature.
Other properties of gases can be inferred from these rules. For example, if the temperature of a gas remains constant, then the kinetic energy of a sample of molecules does not change, no matter how much time passes. Furthermore, the shape and mass of gas particles doesn't determine their kinetic energy; only temperature does this.Learn more in Atoms & Molecules
According to the kinetic molecular theory, particles in a gaseous state, whether in the form of molecules or atomic gases, are in constant, straight-line motion, occasionally bouncing off each other in perfectly elastic collisions which change their direction without slowing them down. It depends on a number of assumptions, such as the idea that the particles are very small compared to the space between them.Full Answer >
The shape of a molecule is important because it is a feature that often determines the fate of a compound regarding molecular interactions. Pharmacology methods have also observed that determining molecular shape is important in drug discovery, virtual screening and predictive toxicology.Full Answer >
Molecular gastronomy is a culinary discipline that involves using scientific knowledge and chemical reactions to create food. It involves the utilization of centrifuges, liquid nitrogen, dehydrators, ultrasounds and other techniques and equipment to prepare food.Full Answer >
A molecular substance is the smallest part into which substances can be divided without losing their properties. It is formed when two or more atoms create a chemical bond. Depending on the number of different atoms forming a molecule, it can be categorized as an element or a compound.Full Answer >
