Answer: they’re the almost the same size almost the same mass and made up of the same materials
Explanation:
If you mean what is in the solution, then that would be water, sugar, and lemonade powder (That is, if it is not homemade). If this is homemade lemonade, then is is water, sugar, lemon juice, and if you've ever seen homemade lemonade, there's also little bits of lemon floating around too, in which case this would technically be a suspension rather than a solution.
Answer:
Explanation:
Evaporation is inhibited by high humidity. Low humidity is as result of hotter temperatures that is temperature when the cup of water is under the sun and vice versa for high humidity.
Relative humidity defined as the amount of water vapor in the surrounding air compared with the maximum possible. At its maximum which is termed saturation, relative humidity is 100% and evaporation is inhibited.
The amount of water vapor the air can hold depends on its temperature. Relative humidity rises at low temperatures for example in an air conditioned environment. As the air temperature declines, sometimes reaching the dew point relative humidity is 100%, and fog may result from the condensation of water droplets if they are small enough to stay in suspension.
Drying is more effective with hot air rather than cold air, because hot air can hold more water vapor. The capacity of air to hold water vapor is based on vapor pressure of water. The liquid and solid phases are continuously giving off vapor because some of the molecules have high enough speeds to enter the gas phase.
Therefore, a cup of water placed in the sun will have a reduced water level compared to that in an air conditioned room.
Molar mass is the mass of one stable molecule of a compound, that cannot join with another molecule of the same kind to form a new one, while an empirical formula is the molecular formula in its simplest form. E.g. empirical formula of ethene is CH2while its molecular formula is C2H4.
Answer:
D. If the distance between the crests of the waves increase, the frequency decreases.
Explanation:
Wavelength is the distance between two successive crests and troughs while frequency is the number of complete cycle per seconds
Velocity = Frequency × wavelength
Frequency and wavelength are inversely proportion
