Question

Piper touches a block of ice and she feels that it is very cold how does she feel the sensation of cold

Answer 1

We feel cold when we touch an object or matter like ice at a lower temperature than our body temperature.

This is because the heat from our body being higher in amount moves to the ice through our skin(by thermal conduction) in order to attain thermal equilibrium between the ice and the body. Due to this loss and absence of heat at that instant on our skin, makes us feel cold.

Answer 2

B. The nerves in the finger detect stimuli and send the message to the brain.
