Which statement best explains why the specific heat of water is higher than the specific heat of most other substances? a) due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change. b) due to the ionic bonding in liquid water, it takes more heat energy to reach boiling. c) because water is a covalent compound, it takes a lot of energy to change its kinetic energy. d) water has a higher density value than most substances and requires more energy to change the temperature.

How to tell if a molecule is polar or nonpolar with electronegativity

Object a has a length of 3 cm, a width of 2 cm, and a height of 4 cm. object b is dropped into a graduated cylinder. it displaces 19 ml of water. the volume of object a is: a: greater than the volume of object b b: less than the volume of object b c: equal to the volume of object b

1. what is the relationship between wavelength and the penetrating power of an electromagnetic wave? a) the penetrating power has no relationship to the wavelength. b) the penetrating power increases as the wavelength increases. c) the penetrating power decreases as the wavelength increases. d) the penetrating power decreases as the wavelength decreases. 2. as ice melts and turns into water, the speed of sound through the material would most likely do what? justify your answer. a) the speed would not change because the material is always water. b) the speed of sound would increase because the density of water is less than that of ice. c) the speed of sound would increase because energy is added to ice in order to make it melt. d) the speed of sound would decrease because sound travels faster through solids than liquids. 3.which of these waves need a medium to travel through? a) sound b) x-rays c) infrared rays d) visible light
