What happens when you touch two hot bowls made of different materials? The wooden and metal bowl are both at the same temperature and HOTTER than your finger. Compare the direction and speed of the heat arrows for the wooden and metal bowl. Explain WHY and what affects HOW the arrows move from the wooden and metal bowl to the finger.

Explanation:

Both metal and wooden bowls are at the same temperature . But wood is non-conductor of heat whereas metal is conductor of heat .

If we touch the wooden bowl , heat flows from hot to cold object . Since the finger is at higher temperature , heat flows from finger to wooden bowl . But , since wood is non conducting , it does not allow heat to be conducted through it . Hence very less heat will be conducted from our finger .

On the other hand , if we touch a metal bowl , heat flows from finger to the metal bowl , without any hinderance . Hence rate  of heat flow will be fast in case of metal bowl . As a result of it , we feel cool in touching metal bowl . This feeling will be absent in case of wooden bowl.

answer: lol

explanation:

lol

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance
