Answer:
As the type of investigation is not discussed, lets answer the question generally.
Explanation:
One of the properties of water is that water in the form of ice is less dense as compared to water liquid water. This property of water lets fishes survive in conditions when the temperature is freezing.
The hydrogen bonds in water make the water turn into a vast, honeycomb structure when the temperature is below 4 degrees Celsius. This causes the ice to float on water and the fishes can stay alive in the liquid water underneath the ice.
Thermal capacity: Water has a great capacity to absorb heat without having to transmit it to another location and without "burning" it. This is very important, for the world we live in, because it allows vegetables to absorb a large amount of solar heat, without combustion, since these vegetables have water in their composition. Furthermore, it is the thermal capacity of water that allows our bodies to be cooled through perspiration.
Specific heat: It refers to the capacity of water to absorb a large amount of energy, to change 1ºC of its temperature. The importance of this is that regions close to bodies of water have a highly stabilized temperature, presenting cooler summers and warmer winters.
Universal solvent: Water has the ability to break an immense number of substances, dissolving them completely. This is very important for countless metabolic processes in our body, in addition to helping us ingest salt and sugar molecules.
Transport: Although it is a liquid, water has an incredible capacity to transport substances, liquids and even particles. Perhaps, this is the most important ability to keep us alive, because it is through the water present in our blood that the blood is able to transport innumerable molecules to our organs, such as proteins, nutrients, oxygen, among others.
Surface tension: This ability allows the water molecules to stay together, completely connected, allowing even insects to be able to pose on its surface. The importance of this is to prevent some liquids from mixing with the water leaving it contaminated.
