Question

1) The smoke speed increases from the chimney if the wind is faster at the end of the upper chimney more than if the winds are slower .
Use the Bernoulli equation to explain this phenomenon.

2)

the specific heat of thees element in J/kg.c are :

iron : 448 , gold : 837 , water : 4186

let's consider that you have 1 kg from each element at temperature 10 C , then you give a heat energy by 100 J.

Arrange the element from top to bottom in terms of temperature increase , then explain with short words what happened

Answer 1

Iron will have the highest temperature rise because it has the lowest specific heat.
