What is the effect of temperature at the rate of diffusion?
the collision theoryFaster diffusion will take place if the surroundings are warmer. Increase in temperature means an increase in molecules' speed (kinetic energy). So the molecules move faster and there will be more spontaneous spreading of the material which means that diffusion occurs quicker.
What is the effect of temperature on the enzymes?
Each enzyme has its' own "perfect" temperature. This varies with the enzyme, the substrate and the environment. In most cases, increasing the temperature above the normal will increase the rate up to a point. Lowering the temperature will slow it down.
What is the effect of temperature on the rate of diastase reaction?
Temperature has a significant impact on the rate of diastase reaction. As temperature increases, the rate of reaction also increases due to higher kinetic energy of the molecules involved. However, there is an optimal temperature range for diastase activity, beyond which the enzyme can become denatured and less effective.
Which graphs likely represents the effect of temperature on photosynthetic reactions?
An exponential graph is likely to represent the effect of temperature on photosynthetic reactions, as the rate of photosynthesis typically increases with temperature up to a certain point before leveling off or decreasing due to enzyme denaturation. The initial increase is due to higher kinetic energy and enzyme activity, while the decrease is a result of enzyme inactivation.
Why do you think increase in 9 degrees above our normal temperature has lethal effect on cells?
An increase in temperature of 9 degrees above normal can denature proteins and disrupt cellular processes in the body. This can lead to cell damage and even cell death. High temperatures can also cause enzymes to lose their shape and function, impairing essential biological reactions.
The ozone layer causes a temperature increase in the?
stratosphere. This temperature increase is due to the absorption of UV radiation by ozone molecules, leading to a warming effect in the upper atmosphere.
What is the effect of gas molecules to the air temperature?
Gas molecules can affect air temperature through their ability to absorb and retain heat. When gas molecules absorb heat energy, they become energetically excited and increase in temperature, causing the overall air temperature to rise. Additionally, certain gases like greenhouse gases can trap heat in the atmosphere, leading to an increase in global temperatures through the greenhouse effect.
Does temperature affect molecules and atoms?
Yes Temperature does effect the movement of molecules and atoms. This is because the warmer the temperature is the easier the molecules and atoms can move, while on the contrary, the colder the temperature is the more difficult it is for the molecules and atoms move around
What is the effect of the temperature on the vapour pressure?
When temperature is increased the amount of molecules evaporated is increasef and as a consequence condensation is also increased so vapour pressure increases.
What effect does temperature increase has on osmosis?
An increase in temperature usually speeds up the rate of osmosis as it increases the kinetic energy of molecules, leading to faster movement across a membrane. However, extreme temperatures can denature proteins and disrupt cell membranes, affecting osmosis negatively.
How does temperature variation effect volumetric measurements?
When temperature increase the volume also increase; but if you think to volumetric titrations the effect is without importance.
Why does temperature effect the rate of osmosis?
Theoretically, the maximum point of increase in the rate of osmosis with the increase of temperature should be the boiling point of water. At this point, the water can not get hotter (without superheating due to the addition of pressure), therefor the rate of osmosis could not be any greater.Yes, increasing temperature would result in an increase in the rate of osmosis, as the water molecules would have more energy and therefore faster Brownian motion. This means the molecules move around a lot faster, so equilibrium would be reached faster.
Effect of temperature on specific heat of material?
An increase in temperature generally causes the specific heat of a material to decrease. This is because as temperature rises, the vibrational energy of the material's molecules also increases, leading to less energy needed to raise the temperature of the material. Conversely, as temperature decreases, the specific heat of a material tends to increase.
What is an effect of heat on the temperature of an object?
Applying heat to an object typically raises its temperature by transferring thermal energy to the object's molecules. This causes the molecules to move faster, increasing their kinetic energy and leading to a rise in temperature.
What is the effect of temperature on viscocity?
As temperature increases, viscosity typically decreases for liquids, as the molecules have more energy and move more freely. However, for gases, viscosity tends to increase with temperature as the gas molecules collide more frequently at higher temperatures.
What is the effect of temperature change on the pressure of a contained gas?
A decrease in temperature will cause the gas molecules to lose kinetic energy and slow down, resulting in a decrease in pressure. Conversely, an increase in temperature will cause the gas molecules to gain kinetic energy and move faster, leading to an increase in pressure. This relationship is described by the ideal gas law.
What effect would lowering the temperature to absolute zero have on the Brownian motion?
All matter has kinetic energy unless it is at absolute zero (-273degrees C). At this temperature this means that there is no movement of molecules which means there is no brownian motion.
