Acontainer holds a sample of hydrogen at 300 k with a pressure of 10 atm when the temperature decreased to 100k and volume remained constant. a. 3000 atm b. 3.3 atm c. 0.1 atm d. 0.3 atmme 40 points.

Answer : The correct answer is B) 3.33 atm .

Given : Initial conditions : ( Volume constant )

Temperature = 300 K Pressure = 10 atm

Final conditions : ( Volume constant )

Temperature = 100 K Pressure = ?

The relation between Temperature and pressure at constant volume is given by a Gas law known as Gay- Lussac Law . This law states that pressure (P) of given amount of gas at constant volume is directly proportional to the temperature (T) . It is expressed as :

C= constant ( at constant volume )

Pressure is in atm and Temperature is in K .

Or it can be written as :

Plugging value of P1 T2 and T2 in this equation .

Multiplying both side by 100 K

P2 = 3.33 atm

Hence answer is B) is correct .

a plasma is a warm ionized gasoline consisting of approximately equal numbers of definitely charged ions and negatively charged electrons. the characteristics of plasmas are notably unique from the ones of ordinary neutral gases in order that plasmas are considered a awesome "fourth kingdom of remember."

a 20-cm-long, cylindrical graphite (pure carbon) rod is inserted into an oxidizing atmosphere at 1145 k and 1.013 x 105 pa pressure. the oxidizing process is limited by the diffu- sion of oxygen counterflow to the carbon monoxide that is formed on the cylindrical surface.
