• 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

Ben(55 kg) is standing on very slippery ice when junior(25kg) bumps into him. junior was moving at a speed of 8m/s before the collision and ben and junior embrace after the collision. find the speed of ben and junior as they move across the ice after the collision .

The direction of the current in an alternating current circuit remains constant. is direct. changes repeatedly. changes randomly.

Acommon technique in analysis of scientific data is normalization. the purpose of normalizing data is to eliminate irrelevant constants that can obscure the salient features of the data. the goal of this experiment is to test the hypothesis that the flux of light decreases as the square of the distance from the source. in this case, the absolute value of the voltage measured by the photometer is irrelevant; only the relative value conveys useful information. suppose that in part 2.2.2 of the experiment, students obtain a signal value of 162 mv at a distance of 4 cm and a value of 86 mv at a distance of 5.7 cm. normalize the students' data to the value obtained at 4 cm. (divide the signal value by 162.) then calculate the theoretically expected (normalized) value at 5.7 cm.
