4. What is conduction?
5. In which states of matter does convection take place?
Answers
Answer:
1) In 1948 the Centigrade scale renamed it the "Celsius" temperature scale and most countries use the Celsius scale. Indian, and several other countries, use the Fahrenheit system of temperature measurement mainly because from the British time only Fahrenheit thermometers were available in India.
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) Human body temperature is 37.0 degrees Celsius or 98.6 degrees Fahrenheit.
4) the process by which heat or electricity passes through a material.
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.
