When is something called hot and when is it called cold?
It’s said than one body has higher temperature than another when there is a heat exchange from the former to the latter. But hot and cold are just sensations or feelings defined by people. Something is called hot when it’s at higher temperature than our body (~37 °C), so a positive heat exchange will take place on contact.
How are the sensations of hot and cold defined?
From here, many hypothetical scales for temperatures are stablished. It’s said than one body has higher temperature than another when there is a heat exchange from the former to the latter. But hot and cold are just sensations or feelings defined by people.
How are hot and cold temperatures related to each other?
So, when we put the hand in the warm from the hot water, our hand will release heat; causing the hand to feel cold. Thus, we can conclude that the more heat it absorbs, the more hotter it is. Whereas the more heat it releases, the colder it is. Hot and cold are relative terms, nothing is absolute hot or cold.
How do you find out how hot or cold you are?
It is actually the amount of heat absorb or release which determine how hot or cold you are. I find this answer by a simple experiment. The experiment just simply putting one in cold water and the other one in hot water. Then, put both hands in warm water.
What degree is considered cold?
The definition of cold is a low temperature or is someone who is not warm and friendly. An example of cold is 32 degree weather.
What is considered cool weather?
Cold weather is defined as a period when the average daily temperature falls below 40°F [4°C] for more than three successive days. These conditions warrant spe- cial precautions when placing, finishing, curing and protecting concrete against the effects of cold weather.
What is considered extreme temperatures?
The definition varies by region, but usually requires temperatures at least 10 degrees above average. However, generally temperatures of 90 degrees or above, accompanied by high humidity levels and resulting in high heat index values, is considered extreme heat.
What is extreme cold temperature?
Hypothermia when exposed to the cold means that your body is losing heat faster than it is able to produce it. The severity of hypothermia can be mild when the body temperature drops below 37C and severe when it drops below 33C. In extreme conditions when severe hypothermia is reached your body will be effected in a number of ways.
