Question

Which of the following influence the physical state of water?

1) number of intermolecular bonds
2) temperature
3) size of the water molecules
4) a and b
5) a and c
6) all of the above

Answer 1

The physical state of water is influenced by the number of intermolecular bonds and temperature, whereas the size of water molecules does not affect it.

Step-by-step explanation:

The factors that influence the physical state of water include the number of intermolecular bonds and the temperature. The size of water molecules does not change and thus does not influence its physical state. Water molecules have strong intermolecular forces of hydrogen bonding, which are significantly affected by temperature changes. Higher temperatures increase the kinetic energy of the water molecules, decreasing the effectiveness of hydrogen bonding, thus altering the physical state of water. Therefore, the correct answer to which factors influence the physical state of water is option 4) a and b.
