a thermometer is placed in water in order to measure the waters temperature. what would cause the liquid in the thermometer to rise? the molecules in the water move closer together. the molecules in the thermometers liquid spread apart. the kinetic energy of the water molecules decreases. the kinetic energy of the thermometers liquid molecules decreases.
Answer
Brief Explanations:
When the water is heated, it transfers heat to the thermometer's liquid. As the liquid gains heat, its molecules gain kinetic energy and spread apart, causing the liquid to expand and rise in the thermometer. When molecules move closer together, it usually indicates cooling. A decrease in the kinetic - energy of water or thermometer liquid molecules is associated with cooling, not the liquid rising in the thermometer.
Answer:
The molecules in the thermometer’s liquid spread apart.
