Carotenoids are the compounds responsible for yellow, orange and red colours in many fruit, vegetable and algal sources. Within each source, carotenoids vary in concentration, proportions and chemical structure, all of which influence how it can be used in a food product.
When heat is added to a substance, the molecules and atoms vibrate faster. As atoms vibrate faster, the space between atoms increases. The motion and spacing of the particles determines the state of matter of the substance. The end result of increased molecular motion is that the object expands and takes up more space.
Making the world better, one answer at a time. When temperature increases, the volume increases. Firstly, we have to know that volume is refering to the space that matter occupies. When temperature increases, the molecules move vigorously because it receives energy from the heat. There will be more collisions among the molecules that causes the molecules to move to more areas in a medium.
