The reason leaves change color is the yellow and orange colors are in the leaf 24/7. The plants make food from the suns energy and use the food to make chlorophyll. When the sun isn't shining so much in autumn the plant can't make chlorophyll and the yellow and orange colors are visible.

What makes fall leaves brighter as they change color?
During the fall season, leaves change color because the green chlorophyll in the leaves breaks down and reveals other pigments, such as reds, oranges, and yellows. This change in pigments makes the leaves appear brighter and more colorful.
What color are the leaves in fall and why do they change color during that season?
During fall, leaves change color to shades of red, orange, and yellow. This change occurs because the chlorophyll in the leaves breaks down, revealing other pigments that were previously masked. This process is triggered by the shorter days and cooler temperatures of autumn.
What do leaves look like when they change color in the fall?

Why do the leaves of most deciduous trees change color during the autumn months?
Deciduous trees change color in autumn because the chlorophyll in their leaves breaks down, revealing other pigments like carotenoids and anthocyanins. This process is triggered by the shorter days and cooler temperatures of fall.
What seasonal change causes deciduous trees to lose their leaves in the fall?
The decrease in sunlight and cooler temperatures that occur in the fall signal deciduous trees to stop producing chlorophyll, the pigment that gives leaves their green color. As chlorophyll breaks down, other pigments like carotenoids and anthocyanins become visible, causing the leaves to change color and eventually fall off.

It is a chemical change anytime you burn something it will most likely be chemical change because something new comes out, for example when you burn the leaves you will get ash which is something the leaves did not have before! your welcome!:)
What change is melting consider because energy is gained by the substance as it changes states?
Melting is known as a phase change because energy is absorbed by the substance as it transitions from solid to liquid. This added energy breaks the bonds holding the particles in a fixed position, allowing them to move more freely.
Is composting leaves a physical or chemical change?
Chemical.
When energy leaves a substance what kind of change is that?
Energy loss is normally associated with a lowering of temperature and is a physical change. However, it can be caused by many other things such as nuclear change or chemical change, both of which are very different from each other and from temperature change.
Why do the leaves of most deciduous trees change color during the autumn months?
Deciduous trees change color in autumn because the chlorophyll in their leaves breaks down, revealing other pigments like carotenoids and anthocyanins. This process is triggered by the shorter days and cooler temperatures of fall.
