What are the 3 phases of energy metabolism?
The three phases of energy metabolism are: Glycolysis, where glucose is broken down into pyruvate. Citric acid cycle (Krebs cycle), where pyruvate is further broken down to produce energy molecules. Electron transport chain, where energy molecules are used to generate ATP, the cell's energy currency.
Which phase changes are endothermic?
Based on chemical properties exothermic phase changes are those that release energy. The exothermic phase changes are gas--> liquid, liquid --> solid, and gas--> solid. Looking at a phase diagram if you are going up the "stairs" the conversions require energy going down the "stairs" energy is released.
What called mobil phase?
The mobile phase is the liquid or gas that flows through the chromatography system, carrying the sample to be separated. It moves over the stationary phase (solid or liquid) and helps separate the components based on their interactions with the stationary phase. The choice of mobile phase depends on the type of chromatography being performed.
Liquid water changes to gas?
When liquid water changes to gas, it undergoes the process of evaporation, in which water molecules at the surface gain enough energy to break free from the liquid phase and enter the gaseous phase. This transformation requires the input of heat energy to overcome the intermolecular forces holding the water molecules together in the liquid state.
Why is bacteria critical to nitrogen cycle?
Because nitrifying bacteria can fix atmospheric nitrogen in to chemical compounds. This nitrogen fixed by bacteria is utilized by plants in making proteins. Again several microbes including bacteria decompose organic matter in to inorganic compounds. Thus nitrogen cycle is maintained by the activity of bacteria, hence these are critical to nitrogen cycle.
Why diffusion is fastest in gas and slowest in solids?
Maybe its the slowest in solids because the particles on it is compressed or tightly squeezed.While in gas, they are the fastest because the particles moves freely because gas is the most spacious matter of the 4.
Which phase of matter has particles moving the slowest?
The solid phase of matter typically has particles moving the slowest compared to the liquid and gas phases. In a solid, particles are closely packed and have limited mobility, resulting in slower movement and vibrating in fixed positions.
What is the order of the phases of water in order from the phase with the slowest molecular movement to the phase with the fastest molecular movement?
The order of the phases of water from the slowest to the fastest molecular movement is solid (ice), liquid (water), and gas (water vapor). In the solid phase, molecules are closely packed and vibrate in place, leading to minimal movement. In the liquid phase, molecules are more mobile and can slide past each other, while in the gas phase, molecules move freely and rapidly, resulting in the fastest molecular movement.
Why is diffusion slowest in solids and fastest in gas?
Maybe its the slowest in solids because the particles on it is compressed or tightly squeezed.While in gas, they are the fastest because the particles moves freely because gas is the most spacious matter of the 4.
Where is the carbon cycle naturally slowest?
The carbon cycle is naturally slowest in deep ocean waters, where carbon can remain sequestered for hundreds to thousands of years before resurfacing. In these regions, carbon can be stored in deep-sea sediments, forming long-term repositories of carbon that contribute to the slow turnover of carbon in the cycle.
What are the phases of matter from fastest to slowest that sound travels through?
The phases of matter from fastest to slowest that sound travels through are solids, liquids, and gases. Sound travels fastest through solids because the particles are closer together and can easily transmit vibrations. In liquids, sound travels slower due to the looser arrangement of particles, and in gases, sound travels slowest because the particles are widely spaced.
What does phase mean in science terms?
In science, phase refers to the physical state of matter, such as solid, liquid, or gas. Phase can also refer to a specific stage in a process or cycle. For example, in biology, phase may describe a stage in the cell cycle.
Does sound travel slowest through gases because the molecules of a gas are far apart?
yes
Particles of a matter move the slowest in a?
solid
Which phase has the most energy?
The phase with the most energy is the gas phase. Gas molecules have higher kinetic energy compared to solid or liquid molecules because they have more freedom to move and collide with each other at higher speeds.
What rule can you state about the relationship between phase changes and temperature?
As the temperature increases, the phases change from having the slowest amount of molecules to having the fastest amount of molecules (solid-liquid-gas)
What element has no gas phase?
Helium is an element that has no gas phase. It remains a gas at all temperatures, without undergoing a phase change.
