The correct answer here is C. Dew forms on the grass.
Water is a polar substance, which means it has many unique properties. One of which, is its ability to adhere and cohere to surfaces and substances. This particular question is asking about the cohesive properties of water, meaning it’s ability to stick to itself (through bonding.) The only answer choice that represents a situation where water is linking up with other molecules of water are dew drops. The water comes together using cohesion to form the drop and hen the water’s high surface tension properties meet the dew drop’s shape. The other answer choices describe alternate processes like: freezing, melting, and evaporation, respectively.
If the Kelvin
temperature of a gas is doubled, the volume of the gas will increase by two. It
follows Charles law where in for a mixed gas of mass, the volume is directly
proportional to the temperature at constant pressure.
