droplets forming on ground
When the temperature falls to 12°C at night and the dew point is at 10°C, condensation will likely occur as the air cools below its dew point. This can result in the formation of dew or frost on surfaces due to the air reaching its saturation point.
The Dew Point is the temperature at which the air is at 100% Relative Humidity. If the temperature fall below the Dew Point, then there is more moisture in the air than it can hold, and water condenses in the form of dew, mist, rain, etc.
Floating water molecules, or water vapor, are always present in the air. The warmer the air is, the more water vapor it can hold. When air cools, it reaches a temperature at which it cannot continue to hold its moisture; this temperature is called the dew point. At this temperature water vapor will condense, becoming a liquid. At night, without the warmth of the Sun, the temperature of the ground and the grass that covers it becomes cooler. If it becomes cooler than the dew point of the air that touches it, condensation will occur. The grass will be covered with droplets of water by morning, even though no rain has fallen during the night. This moisture on the grass is called dew, and it often evaporates in the morning sunlight before we get to see it. (If the temperature at night drops to below freezing, the dew will become frost.) The same thing happens when the glass filled with a cold drink "sweats" on a warm summer day, or when your eyeglasses fog up as you come indoors from the cold.
The temperature at which nitrogen becomes a liquid is 77 Kelvin (-196°C, or -321°F).
Ice crystals would form when the temperature of the air drops to 0 degrees Celsius or below. Since the dew point temperature is -6 degrees Celsius, the air would need to cool further to reach the freezing point of water and allow ice crystals to form.

If the temperature is below the melting point then the element is a solid.If the temperature is above the melting point but below the boiling point, then the element is a liquid.If the temperature is above the boiling point, then the element is a gas.
If the temperature is below the melting point, you know it is in the solid state. If the temperature is below the boiling point, and above the melting point, you know it is a liquid. If the temperature is above the boiling point, you know it is a gas, etc. (Note: melting point is the same as freezing point).
If the dew point temperature is below zero, the air would need to be cooled to that temperature or below for dew to form. At that point, the water vapor in the air would condense directly into ice crystals, in a process called deposition.
Condensation
The state of matter of a substance at room temperature depends on whether the melting and boiling points are above or below room temperature. At room temperature:A substance is solid if both the melting and boiling points are above room temperature.A substance is liquid if the melting point is below room temperature but the boiling point is above room temperature.A substance is a gas if both the melting point and boiling point are below room temperature.
Check the melting point of the substance. If the melting point is below room temperature, then the substance is liquid and if the melting point is above room temperature then it is solid.
The coldest temperature below freezing point is -273 degrees centigrade
When its temperature falls below the boiling point.
