your finger can tell when an object is hot or clod because when a stimulus (the object) touches your skin, receptors transmit it to the brain and your brain sends a reflex reaction to let go

Touch is probably the most fitting.
density
Comparing the density of an object with that of a liquid will determine whether the object will float or sink in the liquid. If the object is less dense than the liquid, it will float; if it is more dense, it will sink.
It is impossible to tell; whether an object floats or sinks depends on its density, not on its weight.
A rainbow appears
The temperature of the object will provide this information.

The surest way to tell if your finger is broken is to have an x-ray done by a doctor. They will be able to tell for sure.
your scene of touch can help you tell how hot or cold an object is.
Meteorologists can tell whether the cloud is cold or not, by the shade of it.
if you spend more time outside, you will after a while get a feeling for how hot or cold it is outside just by peaking out the window. Good luck.
