Diffusion occurs at a slower rate at lower temperatures because the kinetic energy of the molecules decreases. As the temperature drops, molecules move more slowly and collide less frequently, which reduces their ability to spread and intermingle. Additionally, the lower energy levels result in fewer successful interactions between particles, further hindering the diffusion process.
What else can I help you with?
What does lowering the temperature do to the rate of a reaction?
Decrease because particles will move slower causing less collisions.
Labs on temperature temperature affacting rate of photosynthesis?
Generally, it comes down to the basic laws of chemistry. As the temperature increases, particles become more 'excited' and move quicker, therefore increasing the rate of photosynthesis. The opposite happens when temperature decreased, the particles move slower and therefore decreasing the rate of photosynthesis.
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
Does deposition occur faster or slower when water currents are slow?
Deposition occurs slower when water currents are slow because there is not enough energy to transport and deposit sediment effectively. Slow-moving water currents have less ability to erode and carry sediments, resulting in a slower rate of deposition.
If the amount of oxygen reaching the log is reduced what happens to the rate of this chemical reaction?
The rate of the chemical reaction will decrease because oxygen is one of the reactants required for the reaction to occur. With less oxygen available, the reaction will proceed at a slower pace.
How does temperature effect frog heart rate?
the cooler the frog the slower the heart rate, the warmer the faster
What does lowering the temperature do to the rate of a reaction?
Decrease because particles will move slower causing less collisions.
Do the temperature affect the rate of evaporation?
Yes the hotter the weather the faster the evaporation, the colder the slower
Why does the frog heart have lower heart rate than mammalian heart?
Frog's internal body temperature is lower than that of a mammal lower temperature = slower heart rate
What is the rate of amylase activity at 25 degrees Celsius?
the rate would be slower because some enzymes are resistant to temperature change (denaturation)
Do evaporation take place on a cold day?
Yes, evaporation can still occur on a cold day, although the rate of evaporation will be slower compared to a warm day. The cooler air temperature may slow down the process, but as long as there is heat energy available, water molecules can still escape into the air.
Why does a hot cup cool down more quickly from 80degrees-60degrees than 60degrees-40degrees?
The rate of cooling is faster from 80°C to 60°C because the temperature difference between the cup and its surroundings is greater, increasing the rate of heat transfer. As the cup cools down towards 60°C, the temperature difference decreases, causing the rate of cooling to slow down. This results in a faster cooling rate initially and a slower cooling rate as the temperature of the cup approaches 40°C.
When does evaporation occur on a sunny day or a cloudy day?
Evaporation can occur on both sunny and cloudy days. However, it typically happens more rapidly on a sunny day due to the higher temperature and increased energy from the sun. On a cloudy day, evaporation can still occur but at a slower rate because there is less direct sunlight and heat.

Why is the saturated adiabatic lapse rate lower than the unsaturated adiabatic lapse rate?
The saturated adiabatic lapse rate is lower than the unsaturated adiabatic lapse rate because when air is saturated with moisture, the release of latent heat from condensation offsets some of the cooling that would normally occur as the air rises. This results in a slower rate of temperature decrease with height compared to unsaturated air.
What three things can alter the rate of an enzyme?
Three things that can alter the rate of an enzyme are; temperature, pH and substrate concentration. Enzymes will have an optimal temperature and pH, at which they will have the greatest rate. Below or above these optimum conditions, the rate will be slower.
Does water evaporate without boiling?
Evaporation (not vaporization) occur at any temperature; a higher temperature increase the rate of evaporation.
