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.

During which interval are the persons represented by the graph not moving? a) 0 to 0.5 hrs b) 1.5 to 2 hrs c) 2 to 2.5 hrs d) 4.5 to 5 hrs

Which bonds are found inside a water molecule

Place several e-field sensors at a few points on different equipotential lines, and look at the relationship between the electric field and the equipotential lines. which statement is true? 1-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of higher voltages. 2-at any point, the electric field is perpendicular to the equipotential line at that point, and it is directed toward lines of lower voltages. 3-at any point, the electric field is parallel to the equipotential line at that point.
