Answer:

It is often necessary to start campfire with many pieces of kindling rather than large logs because it is easier to ignite smaller pieces than larger pieces. Imagine wanting to light up a pile of clothes and a small piece of a shirt. Which ignites faster? The piece of a shirt, because it is smaller and more likely to burn very quickly. Additionally, people criss-cross these tiny pieces of wood to enable more surface area and to allow more oxygen to pass through. As you know, oxygen is necessary for a flame to ignite.

Allushta [10]
Answer: 94.07%
Explanation:
Percentage yield can be calculated by the formula
%yield = Experimental yield/Theoretical yield x100
Experimental yield = 7.93g
Theoretical yield = 8.43
%yield = Experimental yield/Theoretical yield x100
%yield = 7.93/8.43 x 100 = 94.07%

Sally has touched a hot pan on the stove and burnt her hand. This example shows what type of heat transfer?
Minchanka [31]

Answer:

Transfer of Heat

You might have observed that a frying pan becomes hot when kept on a flame. It is because the heat passes from the flame to the utensil. When the pan is removed from the fire, it slowly cools down. Why does it cool down? The heat is transferred from the pan to the surroundings. So you can understand that in both cases, the heat flows from a hotter object to a colder object. In fact, in all cases heat flows from a hotter object to a colder object.
