Apply the formula for finding the angle: Angle=(30h-(11/2)m( where m stands for minutes and h stands for hours) Hence, 30x11 - 11/2x35 = 330 - 192.5 = 137.5 degrees The reflex angle = 360 - 192.5 degree = 222.5 degrees.
Water at ordinary temperatures contracts and increases in density as it is cooled, like most substances. But at about 4°C it reaches a maximum density and then decreases in density as it approaches the freezing point.
