Glucose and oxygen become carbon dioxide and water. The products have a lower energy content than the reactants.
respiration and microbial degradation of organic matter
If mass were not conserved during changes of state, the amount of matter on Earth would fluctuate as substances undergo phase changes. This would lead to inconsistencies in measurements and make it difficult to accurately determine the total amount of matter on Earth at any given time.
The composition of matter changes during a chemical change as new substances are formed with different chemical properties. In contrast, the composition of matter remains the same during a physical change, with only the physical state or appearance of the substance being altered.
During physical changes, the particles that make up matter remain the same and only their arrangement or state changes. In contrast, during chemical changes, the particles undergo a rearrangement or bonding at the atomic level, resulting in the formation of new substances with different properties.
During phase changes the temperature of a substance does not change.
There are different processes involved during changes in states of matter. The most common ones include melting, evaporation, condensation and freezing.
Yes, matter is transformed during cellular respiration. In this process, glucose and oxygen are converted into carbon dioxide and water, releasing energy in the form of ATP. The atoms in the reactants (glucose and oxygen) are rearranged to form the products, illustrating the conservation of mass where matter is neither created nor destroyed but transformed.
nothings its a dumb question
Changes in the states of matter occur through processes like melting, freezing, condensation, vaporization, and sublimation. These changes involve the rearrangement of particles at the molecular level due to changes in temperature or pressure. During these transitions, energy is either absorbed or released.
Cellular respiration conserves matter by transforming organic molecules, such as glucose, into usable energy in the form of ATP while recycling their components. During this process, carbon atoms from glucose are released as carbon dioxide, which can be used by plants in photosynthesis, thus maintaining the cycling of matter in ecosystems. Additionally, the by-products of cellular respiration, including water and energy, are utilized by other organisms, further integrating the flow of matter within biological systems. Overall, cellular respiration exemplifies the conservation of matter through its continuous cycling and transformation within the biosphere.
In most cases, if matter seems to disappear during a chemical reaction it is because there is an invisible gas produced by the reaction that you did not see or measure.
The oxygen cycle is a biogeochemical cycle that provides oxygen to the Earth. It involves the processes of photosynthesis by plants and phytoplankton, respiration by animals and microorganisms, and the breakdown of organic matter. Oxygen is released into the atmosphere during photosynthesis and taken in during respiration.
