Why does canned air freeze?
Here we go. When canned air is sprayed out, the air is expelled from the can. This removes heat from the can. Since the canned air is under pressure and there is more air in the can than whats surrounding the can, the inside temperature lessens as more air is expelled, removing more heat than the can can get from its ambient environment. The more you spray, the cooler the can can get and even ice up. It works just like a minerature air conditioner.
Which weather tool measures air temperature?
The temperature of the air in the shade. The temperature of the air is a measure of the degree of molecular movement of all the Nitrogen and Oxygen molecules that largely make up air.
How many watts of air conditioning removes one watt of heat?
54 Watts is the eqivianlient to removing 1 watt of heat
What is the index that combines air temperature and relative humidity to determine an apparent temperature?
Heat Index.
What happens when heat is removed from a system?
The water gets colder. If enough heat is removed, including the heat of fusion, the water will freeze. Removing the heat of fusion does not change the water's temperature.
Taking heat out of the air will do what to the temperature?
Removing heat from the air will lower its temperature.
What are you removing when you lower the temperature of water?
you are removing heat!
When you lower the temperature of water what are you removing?
you are removing heat!
Taking heat out of the air will do what to the air temperature?
Removing heat from the air will lower its temperature.
How does the density of air increase or decrease?
By Removing or addng heat
Why is ocean temperature more constant than air temperature?
The specific heat of water is greater than the specific heat of air.
Describe how an gas can become an liquid?
By cooling it. Removing heat. Lowering the temperature. etc.
How is temperature diffrent from heat?
Heat is the cause and temperature is the effect. Heat is energy but temperature is outcome of storage of such heat energy in a body. If same amount of heat is given to the same mass of water and aluminium, then temperature will be more in aluminium but less in water. This is similar to the collecting air in different containers. Air is equivalent to heat and pressure created is equivalent to temperature.
What is the difference between heat and air?
heat is hot, air is cold Heat and air differ in every respect; heat is a form of energy that is transferred by a difference in temperature, and air is a mixture of gases.
What are the four main factors that affect temperature?
* Air temperature * Humidity * Radiant Heat (direct heat radiating from an object such as an oven or even the sun) * Air Velocity
The temperature of the air falls at night because the earth loses heat by?
The temperature of the air falls at night because the earth loses heat by
If the coolant in an air conditioner has a lower temperature the the air in a building then?
Heat will flow from the coolant to the air The coolant will absorb the heat from the building.
