The chemicals in a lightstick give off light as they react. When the lightstick is placed in warm water the glow increases. This is because the A. higher temperature changes the wavelength of light emitted. B. higher temperature catalyzes the reaction. C. activation energy for the process is lowered. D. average kinetic energy of the reactants increases.

the focus of lesson 1 is newton's first law of motion - sometimes referred to as the law of inertia. newton's first law of motion is often stated as. an object at rest stays at rest and an object in motion stays in motion with the same speed and in the same direction unless acted upon by an unbalanced force.

explanation:

measuring things 1 litre of water

when heated, the valance electrons increased their speed and transferred the heat from electron to electron.   i just took the test.

365.25 earth days are in the year of a light year
