Liquid in thermometer chnages on the basis of changing temperature
<h2>Explanation</h2>
Mercury is the most commonly used liquid in a thermometer. The thermometric property of mercury is that it expand or contract with change in temperature. With a rise in temperature, the liquid gets heated and expand and when temperature reduces, the liquid moves down to the tube. This thermometric property of mercury is used to measure temperature.
Protons = +1 negatrons = -1 neutrons = 0 <span>electrons = -1 </span> <span>negatrons are like positrons and they are subatomic particles and are not present in atoms </span> so electrons are negatively charged and are present in atoms
