Athickness of a material is a factor that affects heat conductivity. does heat flow faster through a thick or a thin piece of the same material? the surface area of a material is a factor that affects heat conductivity.  does heat flow faster through a large surface area or through a small surface area?   why?   (hint:   think about the number of particles available to bump into one another).change in temperature is a factor that affects heat conductivity.  will heat flow faster when there’s a large change in temperature or a small change in temperature?

1. Heat flows faster through a thin material.

2. Heat flows through a large surface area.

3. Heat flows faster for a large change in temperature.

Explanation:

Thinking process:

Newton's law of cooling or heat transfer is given by the following equation:

Where Q = Heat change (J)

A = area of hear transfer (m²)

= Change in temperature.

However, for a temperature difference across the wall having a thickness "x"and  a constant surface area A, we get,

Where x = thickness of the material

As we can see, increasing the thickness, x, decreases the heat flux

Increasing the area, A increases the heat flux

A big temperature increase, ΔT results in a large heat transfer.

a rain shadow is a dry region of land on the side that is protected against the prevailing winds of a mountain range. the prevailing winds are the winds that occur most of the time in a particular place of the earth

prevailing winds carry air toward the mountain range. as the air rises up over a mountain range, the air cools, water vapor condenses, and clouds form. on this side of the mountains, called the windward side, precipitation falls in the form of  rain  or snow. this dry air produces a  rain shadow.
