What is Graham's Law of Effusion? What are some examples of the kinetic theory of gases? What is the relationship between Charles law and the kinetic theory of gases? Why does the kinetic theory apply to gases?
What is the average kinetic energy of the molecules in a gas at K? How does the absolute temperature of a substance relate to the average kinetic energy of its molecules? How does a gas expand according to the kinetic molecular theory?
According to kinetic molecular theory, how are gases compared with liquids and solids? Use the terms volume and density to compare gases, liquids and solids in terms of the kinetic An increase in temperature increases the average speed of the molecules and the range of speeds. The average kinetic energy of oxygen molecules and hydrogen molecules will be the same at any particular temperature.
Splitting carbon dioxide CO2 into carbon and oxygen can in fact be accomplished, but there is a catch: doing so requires energy. If hydrocarbon fuels, which produce the greenhouse gas in the first place, supply that energy, thermodynamics tells us that the net result will be more CO2 than you started with.
When gases are diffusing through liquids, for example across the alveolar membrane and into capillary blood, the solubility of the gases is important. The more soluble a gas is, the faster it will diffuse. Carbon dioxide is inherently more soluble than oxygen, and thus diffuses much faster than oxygen into liquid. Porins are types of proteins which form pores of large sizes in the outer membranes of plastids such as chloroplast, mitochondria and the membranes in bacteria.
They help in facilitating the passive transport of small-sized protein molecules. Porins are channels with wide, water-filled pores found in the outer membranes of gram-negative bacteria and mitochondria. Porins are proteins that act as a pore through which molecules pass through cellular membrane. Aquaporins are protein molecules embedded in the cell membrane which allows the flow of water molecules. If we keep in mind that the formula for kinetic energy is 0.
Since the average kinetic energy of oxygen and hydrogen are equal we can write the expression below. However the molecular mass of oxygen is 32 and that of hydrogen is 2. So we can rewrite the above expression. Transforming the formula we obtain the expression below which gives the ratio of the average velocities of oxygen and hydrogen molecules.
The average velocity of hydrogen molecules is 4 times greater than that of oxygen molecules. It is important to note that although the average kinetic energy of all gases is the same at a particular temperature, the average velocity of the molecules is not.
The heavier molecules tend to travel slower relative to the lighter ones. Three gases oxygen, nitrogen and hydrogen are placed in the same vessel at a certain temperature.
