So, a thermometer is placed into a container of water that has been heated. Now if the thermometer is placed in the water, then in actual fact, has the thermometer measured the true value of the temperature of the water?
As Kinetic energy is being shared by the thermometer due to the moving particles that make up the water.
So if this is the case how do we measure how much kinetic energy has been shared?
If the water is heated to say 50 degrees, then in order for their to be thermal equilibrium, donot the mercury particles in the thermometer have to be at the same temperature, and so would not the water particles lose all of their energy when they're sharing it with the thermometer?
Thank you
