Introduction to Mass Transfer

How many atoms contain in a gas at the temperature of 0⁰C and 1 atm

• 6.02 x 10^-23

• -6.02 x 10²³

• 6.02 x 10²³

• -6.02 x 10^-23

6.02 x 10²³ is known best as the ___________’s numbers

• Boyle

• Avogadro

• Mole

• Mass

What is the mass of a mole of water?

• 18.02 g

• 16.00 g

• 1.01 g

• 36.04 g

What is pressure?

• Force exerted on an object

• Force applied perpendicular to the surface of an object per unit area

• Number of particles contain in one mole

• An influence that can change the motion of an object

______ is the pressure relative to the atmosphere

• Vacuum pressure

• Absolute zero

• Absolute pressure

• Gauge pressure

_______ is the unit of pressure in gauge

• Avogadro

• Newton

• Psig

• Psia

What is the purpose of Boyle’s Law?

• Predict the volume of any gas at any given pressure

• Calculate the amount of gas particles contained in one mole of gas

• Assume the pressure at any given temperature

• Predict the volume of any gas at any given temperature

The Charles’ law stated that .......

• As the temperature of gas increases, the pressure increases as well

• As the temperature of gas increases, the volume remains constant

• As the temperature of gas increases, the volume decreases

• As the temperature of gas increases, the volume increases as well

The Avogadro’s Law stated that ......

• As the number of gas particles added to a container is increased the volume will increase as well

• As the number of gas particles added to a container is increased the volume will decrease

• As the number of gas particles added to a container is increased the volume will remain the same

• As the number of liquid particles added to a container is increased the volume will increase as well

The flow of fluids somewhere in between the smooth and orderly pattern and disorder pattern is called as the _____________________

• Turbulent flow

• Transitional flow

• Laminar flow

• In the Middle flow
