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.

option A Due to its polarity and hydrogen bonding water can absorb heat without a significant temperature change.

A water molecule is formed of two hydrogen atoms and one oxygen atom. The atoms are have strong hydrogen bond. Also, water is a polar molecule. there is uneven distribution of density of electrons. This makes the bond even more stronger between the hydrogen atoms and oxygen. Hence, the heat required to raise the temperature of water is high compared to specific heat of other substances.

i think the answer is a, hope this is right, that would be my best guess.

  distance on the y-axis and time on the x-axis.

explanation:

the instantaneous velocity = change in position/time taken

the slope of the graph should give instantaneous velocity.

  slope of a graph = change in value of y -axis / change in values of x -axis

  comparing both the equations

    change in value of y -axis = change in position

  change in values of x -axis = time taken

so position values should be on the y axis and time values should be on the x axis.

distance on the y-axis and time on the x-axis.
