What energy does thermometer needs to work
Physics
ScanSolve AI Answer
A thermometer needs thermal energy to work. This is because it operates by measuring the temperature of an object or substance. The thermometer absorbs or releases thermal energy until it reaches thermal equilibrium with the object it's measuring. This exchange of thermal energy causes a change in the thermometer's material (like mercury or alcohol expanding or contracting), which is then indicated on the scale.
