All elements exist in one of three states - solid, liquid, or gas The standard state is defined at 25 degrees Celcius The state of an element is dependant on its temperature Answer and Explanation: Learn more about this topic: Argon | Definition, Properties & Uses ...
As a result, theaverage winter temperaturedown there is a wicked minus 76 degrees Fahrenheit (minus 60 degrees Celsius). By comparison, the North Pole's mean winter temperature of minus 40 degrees Fahrenheit (minus 40 degrees Celsius) feels downright balmy. Just as there's an Arctic Circle, ...
guanine, and amino acids have also been detected in dilute solutions of NH4CN kept frozen for 25 years at −20 and −78 degrees Celsius, as well as in the aqueous products of MU experiments frozen for five years at −20 degrees ...
How many moles of argon are in bulb?* Start by calculating the constant C, where R = 0.082 L atm mol-1K-1. Keep in mind that 25 degrees Celsius = 298.15 K. C = RT/V = (0.082 x 298.15)/0.5 = 48.9 atm mol-1. Plug that value into the equation for n, and the number of ...
What are the seven elements that naturally occur as diatomic molecules? Standard State: The standard state in thermodynamics is defined as a temperature of 25 degrees Celsius (298.15 K) and a pressure of 1 atm. When we say that a particular substance is present at the standard state, ...
Most elements of the periodic table are solid at room temperature. Some of them are gases at room temperature. The gas elements are all noble gases plus nitrogen, oxygen, fluorine, chlorine and hydrogen. There are only two elements with the liquid state among all elements....
1. Climate change can be a natural process where temperature, rainfall, wind and other elements vary over decades or more. In millions of years, our world has been warmer and colder than it is now. But today we are experiencing rapid warming from human activities, primarily due to burning ...
lungs are large enough to allow them to survive among the thin air at 18,000 feet above sea level. Even camels are remarkable for their ability to tolerate temperatures of up to 120 degrees Fahrenheit (49 degrees Celsius), and survive losing water equivalent to 25% of their entire body ...
Spending an entire day at the welding table is stressful. The UV radiation and the welding fumes are just some of the factors that can be dangerous if you do not have the right protection. The correct welding equipment makes the crucial difference in this area. ...
Fuel cells of this kind operate at very high temperatures (between 700 and 1,000 degrees Celsius). This high temperature makes reliability a problem because parts of the fuel cell can break down after cycling on and off repeatedly. However, solid oxide fuel cells are very stable when in ...
