The short answer is the larger the ice cube the slower it cools water.
Whats really going on has to do with the surface area of the ice in relation to the total mass of the ice. Meaning one large cube will cool water faster than one small cube, however many small cubes will cool faster than one large cube. Unfortunately I can't remember (or readily find) the formula that demonstrates this principle, but suffice it to say the more surface area you can get exposed to the water the faster it will cool. Example: two glasses filled with equal amounts of water at room temperature, take two ice cubes of equal size place one in the first glass, crush the second and place it in the second glass. The second glass will cool faster than the first with the one large cube.
The amount of sunlight, the amount of CO2,the amount of warmth and the amount of water all effect photosynthesis.The amount of sunlight, the amount of CO2,the amount of warmth and the amount of water all effect photosynthesis.
As salt water will kill it quickly in almost all situations, and a regular tap water would keep it living at it's normal rate, I'd say salt would have the greater effect...albeit a negative effect.
*stomata -open-increased transpiration -closed-decreased transpiration *consequence of gas exchange -tradeoff of more gas exchange resulting in more transpiration *environmental factors -humidity -air movement -evaporative cooling -wind stress -intense light/heat
The effect of temperature on the rate of diastase reaction is that it acts as a catalyst. Higher temperatures will speed up the reaction.
A long generation time makes for a slow evolution rate, and a short generation time makes for a fast evolution rate.
what is the conclusion of evaporate rate water
Cooling slows heart rate, thus slowing the pulse rate.
milk is cold. an example of how it affects coffee is this: you have hot water. put an ice cube in that. that's about the same rate as milk and coffee.
solubility generally increases on heating. so sugar cube in boiling water will dissolve fastest.
Black absorbs heat and white reflects it. (other colors will fall somewhere in that range) Therefore, it would make sense that color would effect the rate at which an ice cube melts.
The cooling effectiveness of the chilled water system depends on the water flow. Thus the water flow rate, as well as the temperature of the water, need to be monitored and adjusted to provide the chilling effect.
Say you are cooling liquid A with water. The rate of heat transfer is given by Q = mH2OCpH2OdTH2O = mACpAdTA, where m is the mass, Cp is the mean heat capacity and dT is the change in temperature. So, if you increase m, the mass of water, Q increases (the rate of heat transfer increases) and hence the cooling rate would increase. And if m were to be decreased, the cooling rate would decrease. Strictly speaking, it should be the mass flowrate and not the mass that would be the parameter.
Yes. Other things being equal, the cooling rate should be more or less proportional to the surface area.
This is because of newtons law of cooling, the rate that the water cools is proportional to the difference between the temperature of the water and the temperature of the surroundings. So, as the water is hotter it cools faster, as it cools down the rate of cooling decreases.
Assume question is about evaporative cooling rate Ether had vapour pressure of around 0.7 ATM it would be readily evaporate in air. The ether would be a lot colder than water and cause higher cooling rate. However, if the matter talk about conduction cooling or cooling per unit mass it might be different answer from above.
because of the thermal energy being released from the hot water and dissipated into the air.
Increased surface area increases cooling. Cooling occurs by convection of air above the soup and water vapour loss.
