Review

A transition zone between two air masses is called:

70% Answer Correctly

	fog
	boundary
	front
	thunderstorm

Solution

An air mass is a large body of air that has similar moisture (density) and temperature characteristics. A front is a transition zone between two air masses.

Which of the following substances gives up positively charged hydrogen ions (H⁺) when dissolved in water?

55% Answer Correctly

	base
	alkaline
	acid
	solution

Solution

An acid is a substance that gives up positively charged hydrogen ions (H⁺) when dissolved in water. A base (alkaline) gives up negatively charged hydroxide ions (OH^-) when dissolved in water. pH is a scale that measures of how basic or acidic a solution is. Numbered from 0 to 14, solutions with a pH of 7 are neutral, less than 7 are acidic, more than 7 are alkaline.

Which of the following substances gives up negatively charged hydroxide ions (OH^-) when dissolved in water?

42% Answer Correctly

	acid
	ion
	base
	hydrogen

Solution

What kind of weather front is likely to create clouds and storms?

58% Answer Correctly

	warm front
	temperate front
	cold front
	stationary front

Solution

A warm front is the boundary between warm and cool (or cold) air when the warm air is replacing the cold air. Warm air at the surface pushes above the cool air mass creating clouds and storms.

Which of the following is the formula for work?

47% Answer Correctly

	\(W = {\vec{F} \over \vec{d} }\)
	\(W = \vec{F}\vec{d}\)
	\(W = {F}{d}\)
	\(W = {{F}\over{d}}\)

Solution

Work is performed on an object when an applied force causes displacement along the same vector. Measured in joules (J) or newton-meter (Nm), work is calculated by multiplying force times displacement: \(W = \vec{F}\vec{d}\)
