How it looks. basically the thing that tells you how it change. for example if an ice cube was melted (heat), it only changed physically not chemically as the h20 molecules are still there. however lets say you burn woos— you cant get that would back. its ash now and it has changed chemically.

What is the relationship between KMT and Sea Level Rise?<br> CER format<br> 3-4 sentences
ArbitrLikvidat [17]

Sea level may rise as a result of the expansion of seawater and the melting of land-based ice due to a warming environment.

<h3>What is the sea level?</h3>

The sea level is the fundamental level for calculating height and depth on Earth. Since the ocean is one continuous body of water, its surface tends to seek a constant level. The sea surface is not actually level due to winds, currents, river discharges, fluctuations in gravity, and temperature.

<h3>Why is sea level important?</h3>

People are impacted by sea level changes through flooding, the inability of rivers to empty into the ocean due to the sea being too high, and the surge of seawater onto the land during storms. Our drinking water and the ability to cultivate crops could be harmed if sea water gets into farms and reservoirs.

How does doubling the volume of solvent affect the concentration of the solution?
Alex17521 [72]

Answer:

Molarity is halved when the volume of solvent is doubled.

Explanation:

Using the dilution equation (volume 1)(molarity 1)=(volume 2)(molarity 2), we can demonstrate the effects of doubling volume.

Suppose the starting volume is 1 L and the starting molarity is 1 M, and doubling the volume would make the final volume 2 L.

Plugging these numbers into the equation, we can figure out the final molarity.

(1 L)(1 M)=(2 L)(X M)

X M= (1 L x 1 M)/(2 L)

X M= 1/2 M

This shows that the molarity is halved when the volume of solvent is doubled.
