Is there a third measurement for temperature that they don't use and more?

Celsius, Fahrenheit, and Kelvin. Kelvin is used. It starts at absolute zero. The point where it can get no colder and there is no molecular activity.


Why does a helium tank get colder as you let out more helium?

Letting gas out of a cylinder always causes a cooling. This is the Joule-Thomson effect. As the gas expands work is done against the interatomic/molecular attractions (dispersion forces for helium).


Why is Arizona colder than Minnesota?

Altitude of the particular PART of Arizona OR jetstream activity.


What keeps beer colder aluminum or glass?

Aluminum is a better conductor of heat than glass, so it can help keep beer colder for longer. This means that a beer in an aluminum can will cool down quicker and stay colder compared to the same beer in a glass bottle.


What is the cokdest temperature ever recorded in the universe?

The coldest temperature ever recorded was actually right here on Earth in what is known as an Bose-Einstein Condensate which has a temperature of almost absolute zero, where all molecular activity stops. These are conditions created by man and there is no known colder place anywhere in the universe.


Why does Scandinavia have fewer areas of economic activity than other parts of Europe?

Because of Colder Climates


When temperatures near absolute zero what process causes Atoms to begin to clump?

Condensate is when temperatures are near absolute zero and the process causes atoms to begin to clump. When the temperatures gets colder and colder, the atoms aren't able to move.


What happens to the liquid in the thermometer when it gets colder?

When the liquid in a thermometer gets colder, it contracts and decreases in volume. This causes it to move down the tube of the thermometer, indicating a lower temperature.


Are buffalo plaids good for summer?

Florals are more traditional. Plaids are a heavier design associated with colder seasons.


Why is it colder in the mountains compared to lower elevations?

Mountains are colder than lower elevations because as you go higher in altitude, the air becomes thinner and can't hold onto heat as well. This causes temperatures to drop, making it colder in the mountains.


Why does ice get colder when salt is added to it?

When salt is added to ice, it lowers the freezing point of the ice. This causes the ice to absorb more heat from its surroundings in order to melt, making it feel colder.


Are low degress cold?

Low degrees are associated with cold temperatures, so lower degrees usually indicate colder weather.
