When saturated air is cooled, it simply reaches its dew point. Dew point is simply the temperature at which dew begins to form.
Dew point of saturated air is already pre-determined by how much water vapor the air contains. A state of saturation exists when the air is holding the maximum amount of water vapor possible at the existing temperature and pressure. The higher the dew point, the higher the moisture content of the air. Cooling does not change the dew point of saturated air, rather its the level of saturation.
So if the air has more moisture, dew will form at a higher temperature and vice versa, but dew point is NEVER EVER GREATER than the air temperature.
Answer:
at location 4
Explanation:
it is because the solar eclipse happens when the moon is covering the sun
Answer:
A. Two protons and two neutrons.
Explanation:
Alpha particles are positively charged specie identical to the nucleus of Helium atom.
So we want to know what do electric field lines show except strength of the electric field. Electric field lines are lines that show us the field strength and the DIRECTION of the electric field. If the lines point away from the charge that is producing the lines, the charge is positive, and if the lines point towards the charge that is producing them that charge is negative.
Answer:
Water is a polar molecule
Explanation:
The general solubility rule is that like dissolves like. In short, polar solutes would dissolve in polar solvents. Non polar solutes also dissolves on non polar solvents.
NaCl is an ionic molecule which forms as a result of transfer of electrons from one atom to another. The transfer of electrons makes the atoms oppositely a charged ions and they become polar.
Water is made up of Hydrogen H⁺ ions and hydroxy ions OH⁻. Water is an heteronuclear covalent molecule. Here, there is an unequal sharing of electrons as one atom pulls the shared electron more closer. This leaves a partial negative charge on the more electronegative atom and a partial positive charge on the other.
This polar nature of water NaCl makes dissolution easy.
