Why does ice at 0 degree celsius cools better than water at 0 degree celsius?
Because for ice to transform into water it must absorb heat, called the latent heat of melting. This heat is required to break down the crystalline structure of the ice. The heat is taken from the drinks/food and thus makes them colder than they would be if kept in the same amount of cold water.
Can eruptions cause global cooling?
Yes, volcanic eruptions can cause global cooling by releasing ash and sulfur dioxide into the atmosphere. These particles can scatter sunlight and reduce the amount of solar radiation reaching the Earth's surface, leading to a cooling effect.
The cooling effect of perspiration as it evaporates from the skin is the result of high of water?
The cooling effect of perspiration is due to the high heat capacity of water. As sweat evaporates from the skin, it absorbs heat energy from the body in order to change from a liquid to a gas, resulting in a cooling effect.
What is the name of the cooling effect for moving air at different temperatures?
The cooling effect is called the wind chill effect. It is the increase in the rate of heat loss experienced by a body due to the combination of wind and cold temperatures.
Why did the Mountain Pinatubo eruption result in global temperatures dropping almost two degrees?
The eruption of Mount Pinatubo in June 1991 released vast amounts of sulfur dioxide into the stratosphere, forming a sulfate aerosol cloud that reflected sunlight away from the Earth. This resulted in a temporary cooling effect on the planet's surface, as the aerosols blocked solar radiation. The cooling, which lasted for about 1-2 years, contributed to a notable drop in global temperatures, with estimates of around 0.5 to 1 degree Celsius in the year following the eruption. The overall impact was significant enough to cause a nearly two-degree drop in some regions, particularly in the Northern Hemisphere.
How does an electric fan give cooling effect on a hot day?
The cooling effect is from evaporation mainly. The fan moves an increased amount of air and speeds the evaporation from the skin or other moist surface. A fan blowing on a dry surface will have no cooling effect more than the average temperature of the air. Secondly, another cooling effect happens if the outer temperature is under 36C degree by pushing the hot (36C degree hot) air away from the surface over the surface of body and exchange it by a lower temperature one.
What is the effect on conducting wire when it is passed through 0 degree kelvin that is -273 degree Celsius?

IIfwater is heated from 0 degree to 10 degree effect on volume?
When water is heated from 0°C to 10°C, it undergoes thermal expansion and its volume will increase. The exact amount of volume increase will depend on the coefficient of volume expansion for water, which is approximately 0.00021 per degree Celsius.
What is net refrigeration effect?
The net refrigeration effect is the amount of heat each pound of refrigerant absorbs from the refrigerated space. This heat produces useful cooling.
Does ozone layer has cooling effect?
Ozone does have a cooling effect. It is because of its properties.
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.
What is body temperature in degrees Celsius?
It is 37 degree celsius Your body temperature for Celsius is 37 degrees Celsius.
What is the net refrigeration effect in the refrigeration cycle?
The net refrigeration effect in a refrigeration cycle is the amount of heat absorbed from the refrigerated space by the refrigerant gas as it evaporates, minus the amount of work done on the refrigerant gas during compression. It represents the actual amount of cooling provided by the refrigeration system.
Science fair do heating and cooling effect the strength of glass?
No, heating and cooling does not effect the strength of a glass
Can eruptions cause global cooling?
Yes, volcanic eruptions can cause global cooling by releasing ash and sulfur dioxide into the atmosphere. These particles can scatter sunlight and reduce the amount of solar radiation reaching the Earth's surface, leading to a cooling effect.
What have effect on enzyme?
The major thing that has an effect on an enzyme is heat. If the enzyme is exposed to a large amount of heat than it denatures, which means that it is no longer functional. Enzymes work at their best at an OPTIMUM range, that is at about 30-35 degrees Celsius. The enzyme will denature at about 47-50 degrees Celsius.
