Specific heat capacity can be described as the amount of heat required for raising the temperature of any substance.

The specific heat capacity of water is 4.2 joules per gram at a temperature of 25°C.
The specific heat capacity of water is very high because the hydrogen bonding is very extensive between the molecules of water.

Cohesion

sneha_deepak_08 — 2024-01-25 04:24:48 UTC

Water molecules are attracted to other water molecules due to their ability to form hydrogen bonds with one another.
The cohesive force that exists between water molecules help ensure that as one molecule is pulled into the leaf and evaporates, it pulls along the entire column of water molecules upward.

Adhesion

Water molecules are attracted to other molecules/substances due to their ability to form covalent bonds between the two hydrogen atoms and the one oxygen atom.
Adhesion assists the movement of water containing nutrients that are dissolved in the circulatory system of animals and plants. In plants, the adhesion of water molecules assists in the transport of mineral nutrients in the xylem.

Density Anomalies:

The maximum density of water is 1 gm/cc and is obtained at 4°C. The density of water increases with increase in temperature up to 4°C The anomalous expansion of water helps preserve aquatic life during very cold weather. When temperature falls, the top layer of water in a pond contracts, becomes denser and sinks to the bottom. A circulation is thus set up until the entire water in the pond reaches its maximum density at 4°C.

The dynamic viscosity of water at room temperature is around 1.0 mPa/s. This value decreases when temperature increases, and vice versa.

Drinking water almost always has a very low turbidity. Turbidity meters with a turbidity sensor at the end can be used to provide a reading, and is usually installed in rivers. The amount of light reflected back into the sensor measures its turbidity.

Water can be found in 3 states: solid, liquid and gas. Heat from the sun makes ocean water evaporate into a gas from a liquid, breaking the covalent bonds. When it evaporates, it isolates an individual molecule that flies off the surface as vapor. Because the water molecules absorb energy from heat, these energetic molecules stay farther apart from each other. 540 calories per gram is required for evaporation to occur.
Condensation is the opposite of evaporation. Water molecules lose energy from a loss of heat, making them bond together from a gas into a liquid state. The process forms small droplets of water, surrounding particles of dust or salt. An example would be liquid surrounding a cold glass, and eventually becoming too heavy and falling down. When the temperature of water is lowered below its freezing point (0 degrees C), it expands and freezes into a solid state.
Ice in lakes and streams is more buoyant, therefore it remains at the top.On the other hand, when the temperature reaches above its melting point, it melts. When water in its solid state turns into its gaseous state without going through its liquid state, this process is called sublimation.
Conversely, when it goes from its gaseous state to its solid state, the process is called deposition.
