• The air must be saturated with water vapor, ie there must be a sufficient amount of water vapor in the air. • 2. Water vapor must be rapidly cooled.
• The temperature at which water vapor condenses in the air is called the pink dot.
• Change the dew point value from:
• amount of water in the air
• air temperature
Use of condensation
• Condensation of liquid vapors is the basis of physical methods that separate liquid substances from liquid mixtures and refer to distillation.
• Distillation is the separation of the individual components of a mixture based on different boiling points.
• E. g. : boiling point of water - t1 = 100 ° C
boiling point of ethanol - t2 = 78 ° C
Ethanol is changed separately - its condensation takes place in detail.

Its my hw and idk what to say

in simple terms, the principle states that the buoyancy force on an object is equal to the weight of the fluid displaced by the object, or the density of the fluid multiplied by the submerged volume times the gravitational acceleration, g. this is also known as upthrust.

  the grams     of oxygen gas   that can be produced     is 20.6   grams of o₂

calculation

2liclo₃ →   2 licl + 3 o₂

step 1:   find the moles of liclo₃

moles = mass÷ molar mass

from periodic table the molar mass of liclo₃ =6.9 +35.5   +(16 x3) =90.4 g/mol

moles=38.7 g÷90.4 g/mol=0.4281   moles

step 2:   use the   mole ratio   to calculate the moles of o2

from equation above, liclo₃: o₂   is 2: 3  

therefore the moles of   o₂=0.4281 moles x3/2 =0.6422   moles

step 3: find mass   of o₂

mass= moles x molar mass

from periodic table the   molar mass of   o₂ = 16 x2= 32 g/mol

mass=0.6422   moles   x   32 g/mol = 20.6 grams of o₂

c) up

hope this

electric field is a function of 1/r^2

yes, the force per unit charge for a point charge is inverse square law.
