A thickness 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.) The speed that the heat is conducted through the material is the same for a given thickness. If it takes 0.1 second to increase 5 degrees, if the material is 5 times thicker, it will take 5 times as long ... so the rate is the same for the same given distance
