melting, boiling, and bending are considered physical changes, but burning is a chemical change. explain why this is so.
Naya [18.7K]
<span>So, when you make something boiling or melting, its still the same substance. Water doesn't change into something else, just change its state of matter. When you burn something, one substance reacts with another. For example, when you burn carbon in oxygen, you get carbon dioxide. That's the difference.</span>

You know that energy cannot be created or destroyed, so what happens to it?
riadik2000 [5.3K]
Mass cannot be created nor destroyed as well.

So, energy just goes into other things. 

Example: you are born. You have carbon dioxide in your body, (or star dust). When you die, your body releases that gas.

Make sense?

I hope this helps! (:

What is the frequency of a light that has a wavelength of 3.0 x 10 -7m?
alexdok [17]

Answer:

 frequency of light (f) = 1 x 10¹⁵s⁻¹

Explanation:

Given Data:

Wavelength of light λ = 3.0 x10⁻⁷m

Frequency of light: to be calculated

Formula Used to find frequency:

                                  f = V/λ ........................... (1)

where

f is the frequency

V is the velocity

λ is wavelength

Velocity of light = 3 x 10⁸ ms⁻¹

put the values in equation (1)

                                     f =  3 x 10⁸ ms⁻¹ / 3.0 x10⁻⁷m

                                     f = 1 x 10¹⁵s⁻¹

   So the frequency of light =  1 x 10¹⁵s⁻¹
