Because of water's specific heat capacity, it takes longer for the water to heat up. This is useful because if water heated up quickly, then the ocean would be literally boiling, and it would evaporate into the atmosphere.
Answer:
This is a verified chemical change. On the other hand, if you add red ink to water, it will turn red. However, we would classify that as a physical change. To conclude, color change is a great indicator that change has occurred.
Explanation:
This is since there are examples of color change being an indicator for both of them. For instance, when you heat the blue copper(II) hydroxide solution, you'll eventually end up with a black copper oxide (
Cu
O
) solution. This is a verified chemical change. On the other hand, if you add red ink to water, it will turn red. However, we would classify that as a physical change.
To conclude, color change is a great indicator that change has occurred. However, it does not tell you which type of change might have occurred. You will want to use better indicators - like release of heat - to guide you with that.
Hope that helped :)
