What is most likely reason that red liquid inside of a thermometer moves up when heated? A. Moves faster and comes together b. Moves faster and spreads apart c. Move slower and comes together d. Moves slower and spreads apart
B. Moves faster and spreads apart
When the red liquid inside a thermometer is heated, its particles gain energy and move faster, causing the liquid to expand and move up the tube of the thermometer. This is because as the liquid heats up, the particles move farther apart, increasing the volume of the liquid and causing it to rise.
