What is the great cooling effect produced by water evaporating, and how does it relate to its high evaporation rate?
The great cooling effect produced by water evaporating is called evaporative cooling. When water evaporates, it absorbs heat from its surroundings, causing a cooling effect. This cooling effect is related to water's high evaporation rate because the faster water evaporates, the more heat it can absorb, leading to a greater cooling effect.
Newton's law of cooling applies to objects that are?
Newton's law of cooling applies to objects that are both heating and cooling. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings.
What is the relationship between temperature change and time in Newton's law of cooling graph?
In Newton's law of cooling, the relationship between temperature change and time is exponential. As time increases, the temperature change decreases at a decreasing rate. This means that the rate at which the temperature changes slows down over time.
Which change of state causes cooling to the atmosphere?
The change of state from gas to liquid, also known as condensation, causes cooling to the atmosphere. During condensation, water vapor in the atmosphere releases heat energy as it transforms into liquid water, resulting in a cooling effect.
What is the process of cooling down of water vapour called?
The process of cooling down water vapor to form liquid water is called condensation. This occurs when the temperature of the water vapor drops below its dew point, causing it to change phase from gas to liquid.
Why does the adiabatic rate of cooling change when condensation begin?
When water changes state from a vapor to a liquid it release heat.

What is newton's cooling law?
rate of change of cooling is directly proportional to the temperature distance between the body and the surrounding at the instant.
Why is there a difference in the rate of heating water and the rate of cooling water?
The difference in the rate of heating and cooling water primarily stems from the specific heat capacity of water, which is relatively high. When heating, water absorbs energy, leading to an increase in temperature, while cooling involves the release of that energy. Additionally, factors like convection currents and evaporation can enhance cooling, making it occur more rapidly than heating under similar conditions. Overall, these thermodynamic properties result in distinct rates for heating and cooling processes.
Is cooling water vapour a chemical change?
yes it is
How would bigger mass in the water affect the cooling rate?
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.
What conclusion can you make about the effect of the evaporation on cooling?
what is the conclusion of evaporate rate water
Will the surface area of a container affect the cooling rate of water?
Yes. Other things being equal, the cooling rate should be more or less proportional to the surface area.
Newton's law of cooling applies to objects that are?
Newton's law of cooling applies to objects that are both heating and cooling. Newton's Law of Cooling states that the rate of change of the temperature of an object is proportional to the difference between its own temperature and the temperature of its surroundings.
Why does hot water cool quicker in the first 5 minutes?
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.
Is cooling liquid water to form ice a chemical change?
No. Freezing is a physical change.
What is the relationship between temperature change and time in Newton's law of cooling graph?
In Newton's law of cooling, the relationship between temperature change and time is exponential. As time increases, the temperature change decreases at a decreasing rate. This means that the rate at which the temperature changes slows down over time.
