F.Answer the following questions in one word or a sentence.
1. Which scale of temperature is used in India?
2.What is the working principle of a liquid thermometer?
3.What is the average temperature of the human body in the Celsius and Fahrenheit scales
4.What is conduction?
5. In which states of matter does convection take place?
Answers
Answer:
1. The Celsius scale is particularly being used all around the globe for business and logical estimations of temperature. In India, the Celcius scale is in wide use.
2. Liquid-in-glass thermometers are based on the principle of thermal expansion of substances. A liquid in a glass tube (called a capillary) expands when heated and contracts when cooled. A calibrated scale can then be used to read off the respective temperature that led to the corresponding thermal expansion.
3. The average normal body temperature is generally accepted as 98.6°F (37°C). Some studies have shown that the "normal" body temperature can have a wide range, from 97°F (36.1°C) to 99°F (37.2°C).
4. the process by which heat or electricity is directly transmitted through the material of a substance when there is a difference of temperature or of electrical potential between adjoining regions, without movement of the material.
the process by which sound waves travel through a medium.
the transmission of impulses along nerves.
5. Convection occurs when particles with a lot of heat energy in a liquid or gas move and take the place of particles with less heat energy. Heat energy is transferred from hot places to cooler places by convection. Liquids and gases expand when they are heated.
