Explanation:
chemical changes
>produce new substances w/ different chemical structure/ properties
> thermal energy can be used to BREAK bonds (endothermic)
>thermal energy can be transferred to a chem rxn to help form new products (endothermic)
> heat can be released by an exothermic chemical reaction (excess energy- the total energy used to break bonds is less than energy released in forming new bonds)
physical changes
>does not result in new substances (typically changes in state- solid, liquid, gas)
> thermal energy can be transferred to EVAPORATE water (add thermal E... water (liquid) to steam (gas)) or FREEZE water (remove thermal E... water (liquid) to ice (solid))
Answer:
False.
Explanation:
An aurora is a natural electric phenomenon that creates bright and colorful light displays in the sky. These dramatic and colorful lights are created when electrically charged particles from solar winds enter the Earth's atmosphere and interact with gases in the atmosphere.

I am going to say A
Explanation:
solids are normally close and tightly packed molecules and while ice is in solid form,so is it.
Let me know if i was right! Hope this helps! :)
Answer:
The width of the slit is 0.167 mm
Explanation:
Wavelength of light, 
Distance from screen to slit, D = 88.5 cm = 0.885 m
The distance on the screen between the fifth order minimum and the central maximum is 1.61 cm, y = 1.61 cm = 0.0161 m
We need to find the width of the slit. The formula for the distance on the screen between the fifth order minimum and the central maximum is :
where
a = width of the slit
a = 0.000167 m
a = 0.167 mm
So, the width of the slit is 0.167 mm. Hence, this is the required solution.
