How does chain-branching affect the contact surface area between molecules?
Chain-branching increases the contact surface area between molecules, leading to stronger interactions and potentially altering the properties of the material.
Do isomers boiling points increase or decrease with more branching?
Generally, the boiling points of isomers decrease with increased branching. This is because increased branching reduces the surface area available for intermolecular forces to act on, resulting in weaker van der Waals forces between molecules. As a result, the molecules are easier to separate, leading to lower boiling points.
How does branching affect the boiling point of a substance?
Branching in a molecule generally lowers the boiling point of a substance. This is because branching reduces the surface area available for intermolecular forces to act upon, making it easier for the molecules to escape into the gas phase.
How does surface area affect the rate of cooling of soup?
A larger surface area allows for more heat to be transferred from the soup to the surrounding environment, resulting in faster cooling. This is because a larger surface area increases the contact between the hot soup and the cooler air. Conversely, a smaller surface area would slow down the rate of cooling as there is less area for heat exchange to occur.
Why grinding help a solution dissolve rapidly?
Grinding increases the surface area of the solute particles, which allows for more contact with the solvent. This increased surface area facilitates faster dissolution since more solute particles can come into contact with the solvent, leading to a quicker saturation and dissolution process.
How does chain-branching affect the contact surface area between molecules?
Chain-branching increases the contact surface area between molecules, leading to stronger interactions and potentially altering the properties of the material.
As a cell increases in size the a. metabolic rate increases. b. surface area to volume ratio increases. c. volume increases and the surface area increases. d. surface area increases and the volume d?
As a cell increases in size the volume increases much faster than the surface area. The possible answer is C.
Does the cristae increase or decrease the surface area of the inner membrane?
Cristae increases the surface area of the interior membrane of the mitocondria.
What happens to a cell ratio of surface area to volume as the cells volume increases rapidly than its surface area?
The cell's ratio of surface area to volume would decrease if its volume increases more rapidly than its surface area.
When the volume of a cube increases does the ratio of its surface area to its volume decrease?
If the length of the cube's side is 'S', then the surface area is 6S2 and the volume is S3 .The ratio of surface area to volume is 6S2/S3 = 6/S .This number is inversely proportional to 'S'. So as the side increases ...causing the volume to increase ... the ratio does decrease, yes.
What happens to a cell's ratio of surface area to volume as the volume increases more rapidly than its surface area?
As volume increases surface area increase, but the higher the volume the less surface area in the ratio. For example. A cube 1mmx1mmx1mm has volume of 1mm3 surface area of 6mm2 which is a ration of 1:6 and a cube of 2mmx2mmx2mm has a volume of 8mm3 and surface area of 24mm2 which is a ratio of 1:3.
What happens to the surface of the cell as the volume of the cell increases?
As the volume of a cell increases, the surface area of the cell also increases, but at a slower rate. This can lead to a decrease in the surface area-to-volume ratio of the cell. A decreased surface area-to-volume ratio can impact the cell's ability to efficiently exchange materials with its environment, potentially affecting its overall functioning.
How is a cells potential growth affected by its ratio of surface area volume?
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.
Why air tubes in lungs branch again and again?
The branching of air tubes in the lungs allows for the efficient distribution of air to all parts of the lungs, ensuring that oxygen can reach the smallest air sacs where gas exchange occurs. This branching pattern increases the surface area available for gas exchange and allows for a greater volume of air to be accommodated in the lungs.
What are the two ways pressure increases?
Pressure can increase due to an increase in the force exerted on a surface or a decrease in the surface area over which the force is distributed. This is described by the equation pressure = force/area.
How does boiling and melting points vary as branching in a hydrocarbon chain increase?
As branching increases, the size of the molecule is more (when compared to its unbranched isomer). Hence there are more number of molecules per unit area / volume. Hence the melting point increases, as branching increases.
How does cell growth affect the cell surface to volume ratio?
The rate at which the cell increases in size depends on the DNA. The ratio of the surface area (calculated: length x width x # of sides) is divided by the cell volume (calculated: length x width x height). THE VOLUME OF THE CELL INCREASES MORE RAPIDLY THAN THE SURFACE AREA, CAUSING THE RATIO OF SURFACE AREA OVER VOLUME TO DECREASE. This decrease causes cell malfunction. If the cell volume increases too much, then the ratio will decrease causing problems for the cell's regular functions.
