When the diaphragm contracts , air pressure in the chest increases . True or False ?
nexus9112 [7]

Answer: False

 

When the diaphragm contracts, the muscles will also contract and pull upward and increase the size of the thoracic cavity thus decreases air pressure inside during inspiration. After the diaphragm contracts, it goes to relaxation, the muscles will also relaxed. It gets looser and return to its original position higher up in the chest. This increase the pressure in the chest, which force the air in the lungs out through the nose.

Explain why your hands feel cool if they get wet?
Furkat [3]

Answer:

How hot or cold you feel depends on the rate at which your body is losing heat to the environment

Water on your skin acts pretty much like sweat. Water is more thermally conductive than air; therefore, the skin loses its heat to it much faster than it would to air.

Also, because water evaporates, it carries heat away from the skin and this increases the rate at which the skin loses its heat. The faster heat loss from the skin to water is what makes us feel cold when we are wet. But of course, the temperature of water has to be lower than the skin for this to occur, which is usually the case.
