Which one is NOT one of the properties of water?

marysya [2.9K]

Answer:

a. the frozen form is more dense than the liquid form

Explanation:

The remaining properties are exhibited by water and are described as follows.

b. the frozen form is less dense than the liquid form

1. Water freezes to form ice.

2. When ice is put in water, ice starts floating in water and is visible.

3. If the density of ice was greater than water, ice would have got sunk and go downwards in the water body.

4. Hence, ice which is frozen form of water, has less density than water.

c. water is a solvent

1. The solvency is defined as the ability of a liquid to dissolve a substance.

2. Water is called the universal solvent. This means water can dissolve almost all types of substances.

3. Water is a polar solvent. The polar water molecules have the ability to break down both ionic and covalent bonds.

d. water has a high heat capacity

1. This is defined as the amount of heat needed by 1 gram of a substance so that its temperature is changed by 1 degree centigrade. The heat can either be gained or lost for the temperature to change.

2. The heat required by 1 gram of water to either increase or decrease the temperature of water is called the heat capacity of water.

e. water has a high heat of evaporation

1. This is defined as the amount of heat needed by 1 gram of a substance so that it changes its state from liquid to gas.

2. The heat required to convert 1 gram of water into vapours is called the heat of evaporation of water.

3. 1 g of water when heated at 25 centigrade needs 580 calories of heat to convert into gas.

All the above properties of water show the importance of water for life.

Rabbits, turtles, fish, humans, and whales all share certain characteristics but also differ from each other. All of these speci

Delvig [45]

The levels of organisation are

Domain: Eukarya

Kingdom Animalia

Phylum :Chordata

Explanation:

They all share these levels of organisation because;

for the Domain Eukarya, they have;

→multi-cellular cells containing nucleus; and other membrane bound organelle.e.g Mitochondrial.

→their DNA located in the nucleus packaged as linear chromosomes bounded by histone proteins.

→mode of reproduction which is sexual.

They share Kingdom Animalia because;

→they have multi-cellular, specialised cells, bounded by plasma membranes.

→they have specialized tissues, organs, and system.

→they all undergo heterotrophic mode of nutrition as evident in the question 'that they must consume plants and animals as source of energy'

→they exchanged communication by nervous ssytem and 

→ use homeostatic mechanisms to regulate water balance of the body through the kidney.

→Humans,Rabbits,and whales are VIVIPAROUS; they give birth to young ones alive.

→Most fishes lay eggs to reproduce, they are said to be Ovoviviparous.

They belong to phylum Chordata because ;

→they all have noto chord; which serve as template for axial skeleton.

dorsal hollow nerve cord -template for the brain and spinal cord

→pharyngeal slits- templates for gill aches in bony fishes and components of inner ear in land animals.

→ tail length varies in these organisms.
