What is the process of changing directly from a gaseous state to a solid state called?SublimationLiquefactionSolidificationDepositionQuestion 3 of 154. Which of the following is NOT a factor that affects atmospheric pressure?AltitudeGravityAir densityTemperatureQuestion 4 of 155. Which of the following is NOT a factor that affects the rate of evaporation?TemperatureWind speedHumiditySurface areaQuestion 5 of 156. Why does water evaporate even when it is not boiling?Because particles of matter are always moving and have different amounts of kinetic energy.Because of the force of gravity.Because the air is always saturated with water vapor.None of the aboveQuestion 6 of 157. Which of the following will evaporate the fastest?A puddle on a hot, sunny dayA puddle in a dry environmentA puddle in a humid environmentA puddle on a cold, cloudy dayQuestion 7 of 158. Why do clothes dry faster on a windy day?Because the wind increases the surface area of the clothes.Because the wind decreases the humidity around the clothes.Because the wind increases the temperature of the clothes.All of the aboveQuestion 8 of 159.
