In conduction, the thermal energy of a particle is transferred to other particles throughout the solid. The particles with more energy are transferred to those with less.
It is advisable not to wash the thermometer and hot water because it made cause the thermometer to break and mercury to leak out from it... it can also damage the accuracy of the thermometer
Thermal energy is THE MEASURE OF TEMPERATURE IN A SYSTEM.
Thermal energy refers to the internal energy that is present in a system as a result of its temperature. The motion of the particles of an object depends on the temperature of the object and the higher the temperature, the faster the movement of the particles. The reverse is also true.
