When water evaporates (which involves breaking of hydrogen bonds), it removes energy from its surroundings in a fashion that renders water an Excellent coolant.
Within water molecules, polar covalent connections are created between the hydrogen and oxygen atoms. The shared electrons are attached to the oxygen atom for a longer period of time than they are to the hydrogen atoms. A water molecule has no overall charge, but each hydrogen atom has a little positive charge, and each oxygen atom has a slight negative charge. The slightly positive hydrogen atoms repel one another and form the distinctive shape as a result of these charges. The positive and negative charges in the various regions of each water molecule cause them to attract other water molecules. Additionally, water forms hydrogen bonds with other polar molecules (like sugars) by attraction.

The sum of the formal charges on the hydrogen atoms (3 x zero) plus one for the oxygen gives a total charge of +1, which agrees with the overall charge.
Atoms are electrically neutral because they have equal numbers of protons (positively charged) and electrons (negatively charged).
Answer :
Charles's Law : It is defined as the volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
Mathematically,
Boiling water bath Cool bath 1 Cool bath 2
Temperature (⁰C) 99 17 2
Temperature (K)(T) 273+99=372 273+17=290 273+2=275
Volume of water 0.0 27.0 34.0
in cool flask (mL)
Volume of water= 135.8 135.8 135.8
Air in flask (mL)
Volume of air 135.8 108.8 101.8
in cool flask (V)
The graph volume versus temperature for a gas is shown below.
Answer:
Boyle's law: A) Pressure and volume.
Charles's law: B) Temperature and volume.
Gay-Lussac's law: C) Pressure and temperature.
Explanation:
Hello,
In this case, since Boyle's law study the relationship between pressure and volume at constant temperature as an inversely proportional one, we have:
Boyle's law: A) Pressure and volume.
Next, since the Charles' law study the relationship between the volume and the temperature at constant pressure as a directly proportional one, we have:
Charles's law: B) Temperature and volume.
Then, since the Gay-Lussac's law study the relationship between the pressure and the temperature at constant volume as a directly proportional one as well, we have:
Gay-Lussac's law: C) Pressure and temperature.
Best regards.
