if we melt ice with heat why temperature remain constant on thermometer. |
|
Answer» The heat energy used to change the form this heat energy is hidden so this heat is known as latent heat and because this is a hidden heat so yher is no change can be seen in temperature on thermometer Because the heat energy will starts to broke the solid particles to convert them so temperture remains constant on thermometer Because the heat particles broke The heat os utilised in changing state of matter thus no change in temp. Due to latent heat |

What are the importance of tissues |
| Answer» Anything entering or leaving the body crosses at least one layer of epithelium. As a result, the permeability of the cells of various epithelia plays an important role in regulating the exchange of materials between the body and the external environment and also between different parts of the body. All the epithelium is usually separated from the underlying tissue by an extracellular fibrous basement membrane..Functions of epithelial tissues:\tThey form the outer lining of the skin and protect the underlying cells from drying, injury and chemical effects.\tThey form the lining of mouth and alimentary canal and protect these organs.\tThey help in absorption of water and nutrients.\tThey help in elimination of waste products.\tThey form secretory function by secreting a variety of substances such as sweat, saliva, enzymes, etc. | |
