A skillet is lined with a thin layer of cooking oil followed by a layer of unpopped popcorn kernels. Upon heating the kernels, all pop thereby escaping the skillet. Which of the following physical and/or chemical changes occurred?
A. The water within each kernel is heated to the point that it would turn into water vapor as the kernels popped (physical change). B. The starches within the kernels are cooked by the high temperatures (chemical change). C. Both A and B occur. D.

Determine the latitude of the tangent rays of the Sun in the Northern Hemisphere on the following days of the year, then indicate if latitudes north of the tangent rays in the Northern Hemisphere are receiving 24 hours of daylight or 24 hours of darkness. Remember, the tangent rays and circle of illumination will be the same number of degrees of latitude away from the North Pole as the declination of the Sun is from the equator. If the declination of the Sun is north of the equator, it is the high-Sun season (“summer”) in the Northern Hemisphere; if the declination of the Sun is south of the equator, it is the low-Sun season (“winter”).
