Answer:
Because it goes through the process of sublimation.
Explanation:
It is gas such as oxygen,nitrogen,hydrogen,etc
Answer:
See explanation
Explanation:
From the information provided;
P1 = initial pressure = 758.0 mmHg
T1 = Initial temperature = 32.7°C + 273 = 305.7 K
V1 = Initial volume?
P2 = Final pressure = 364.2 mmHg
V2 = Final volume = 425 L
T2= Final Temperature = 3.10°C + 273 = 276.1 K
P1V1/T1 = P2V2/T2
P1V1T2 =P2V2T1
V1 = P2V2T1/P1T2
V1 = 364.2 * 425 * 305.7/758.0 * 276.1
V1 = 226. 18 L
B) Total pressure = 100.0 kPa
Pressure of Helium = 83.1 kPa
Pressure of carbon dioxide = 0.1000 kPa
Pressure of oxygen ?
From Dalton's law of partial pressures;
PT = P1 + P2 +P3 +.........
Hence;
Poxygen = 100.0 kPa - (83.1 kPa + 0.1000 kPa)
Poxygen = 16.8 kPa
Answer: False
Explanation:
Viscosity is defined as the resistance to the flow of a fluid. More are the inter molecular forces between the particles of a liquid, the more the viscosity of the liquid and thus it will flow slowly.
Example: Oil is more viscous than water and thus flows slowly than water.
Effect of temperature: Viscosity decreases with increase in temperature as the forces among particles decrease due to increase in kinetic energy and thus they offer less resistance to flow.
Thus viscosity of liquids will decrease with increasing temperature.
