Question

water molecules in cold room temperature and hot water Cold Wata Room Temperature Water Hot Water Thermometers have a very thin tube inside of them that stretches up from a round bulb which holds most of the liquid a Why does the red liquid move up the tube when a thermometer is heated When heated the molecules in the liquid inside the thermometer get a little further apart Because the liquid takes up more space the red line moves up in the tube MATERIA AMM b Why does the red liquid move down the tube when a thermometer is cooled When cooled the molecules in the liquid inside the thermometer get a little closer together Because the liquid takes up less space the red line moves down in the tube If two thermometers have different liquids in them the liquids can move to different heights in the thermometers even if they are measuring the same temperature Why does that happen
