This question deals with the effect of temperature on the rate of reaction.
It is a general rule that as temperature increases, rate of reaction also increases. This is because of how chemical reactions take place.
Every chemical reaction has a certain activation energy.This is the specific energy that two particles in the reaction mixture need before they can react with each other. A lot of the energy that particles in a reaction mixture use to react comes from the heat around them.
Now think logically, if the temperature of a reaction mixture is higher, more of the particles within it will have the energy they need to react - the activation enthalpy. Because more of the particles have the required energy, they react quicker because when two of the particles collide, it is more likely that they will react successfully due to their higher energy.
Hope this helps!
Since an iceberg is fresh water in a frozen state, it would float. If the temperature were above the freezing point of 32 degrees Fahrenheit, it would also slowly melt.
The length of the air column is usually increased slowly because of resonance.
slowly
the most importance is LOVE first and then slowly slowly kissing,touching and so on....
it will evaporate
If you mean 0°Celsius, that equates to +32°F, and yes, ice could melt, albeit slowly.
A psychrotroph is an organism that grows slowly in the cold but has an optimum growth temperature of around 32 degrees Celsius. Psychrotrophs can survive and even grow at refrigeration temperatures, making them a concern for food spoilage in cold storage environments.
At lower temperatures like 10 degrees Celsius, molecules move more slowly, resulting in decreased diffusion and a longer time for the smell of cologne to reach you compared to higher temperatures.
I am going to assume your talking about Fahrenheit. Which would take 32 degrees Fahrenheit for ice to begin to melt (albeit slowly). If you come from a place that uses Celsius its understandable to be confused by this at it will seem illogical as Celsius is a simpler and a more logical way to measure temperature.
Dawdle is to take ones time; proceed slowly.
When acid is diluted, the concentration of acid particles decreases. This can decrease the rate of reaction because there are fewer acid particles available to participate in the reaction. Thus, the reaction can proceed more slowly compared to when the acid is concentrated.
At 0 degrees Celsius, amylase enzyme activity decreases significantly due to the cold temperature slowing down the kinetic energy of molecules, causing them to move more slowly and reducing the enzyme's effectiveness in catalyzing reactions. Amylase works optimally at higher temperatures closer to body temperature.
Agar is cooled below 50 degrees Celsius to prevent it from solidifying too quickly. This allows time for the agar to be poured into Petri dishes and to evenly distribute any added nutrients or samples before it solidifies. Cooling it slowly also helps to avoid the formation of air bubbles in the agar.
This is not a question
The molecules in an ice cube at 0 degrees Celsius move more slowly and are more orderly arranged in a solid structure than the molecules in a substance at 20 degrees Celsius, which are moving quicker and have more kinetic energy. The increased kinetic energy at 20 degrees Celsius results in the substance being in a liquid state instead of a solid state like the ice cube.
If 50 grams of water saturated with potassium chlorate at 23 degrees Celsius is slowly evaporated to dryness, approximately 6.5 grams of the dry salt (potassium chlorate) would be recovered. This is based on the solubility of potassium chlorate in water at that temperature.
300 degrees Fahrenheit = 148.9 degrees Celsius
