Exam 5: Waterʹs Unique Properties

As water cools from room temperature,it contracts in volume and reaches its greatest density at 4°C (39°F).

A line on a weather map that is marked with small triangular spikes designates a warm front.

Warmer-than-average surface water temperatures between Africa and the Caribbean are associated with a greater frequency of Atlantic hurricanes.

When temperatures are below freezing,the temperature at which air becomes saturated leading to the formation of frost is the .

Derechos are slow moving,curved-line winds.

The phase change from liquid water to water vapor involves more energy than the phase change from ice to water.

Fog is a cloud layer on the ground restricting visibility to less than 1 km (3,300 ft).

The wet adiabatic rate is ______than the dry adiabatic rate because______ .

Which of the following best describes a cloud?

The lowest temperature of a typical day also corresponds with the lowest relative humidity.

The dew-point temperature occurs when relative humidity is approximately 80 -85%.

The Saffir-Simpson Hurricane Wind Scale is based on damage estimates from hurricane force winds.

In winter,freezing water can break pipes and even crack engine blocks.Why does this happen?

Which of the following are CORRECTLY matched?

Convectional lifting results when air from different directions flows toward an area of low pressure.

The water vapor content of the air is termed humidity.

The highest rainfall in the world occurs in an area whose rainfall is generated by

Severe weather events associated with midlatitude cyclones have little impact on humans since they largely occur in scarcely populated areas.

Clouds with the prefix alto- are high clouds composed mostly of ice.

The fact that water expands as it freezes allows it to break pipes and damage roads.
