in thermometer, liquid instead of gases and solids are used. Explain why?
Answers
Answer:
Most metals are good conductors of heat and they are solids at room temperature. Mercury is the only one in liquid state at room temperature. It's used in thermometers because it has high coefficient of expansion. Hence, the slightest change in temperature is notable when it's used in a thermometer.xplanation:
Answer:
Because liquid has a property of expansion.
Explanation:
In thermometer ,mercury is used because it is a metal having property of low melting point and it melts at room temperature also it expands in the presence of heat.
If we use solid and gases they do not expand much may gas expand but they have not fixed volume so they move in whole thermometer which is not practical.
hence, we used liquid (mercury) as thermometer for using purpose.
