How does the temperature of a tub of hot water as measured by a thermometer differ from the water's temperature before the measurement is made?
The temperature of the water in the tub before the measurement is the same as the temperature measured by the thermometer once it has equilibrated. However, there may be a small delay between when the thermometer is first introduced and when it reaches the actual water temperature due to thermal equilibrium.
How do you know if a frog is a water frog?
Well you can' t see that from the outside. Scientists used to think (many decades ago) frogs with a warty skin lived on land, and frogs with smooth skin lived in the water.
