The crystals start to appear show that crystallization has just occurred.
<h3>What is crystallization?</h3>
Crystallization refers to the process by which a solid separates from the solution. Crystallization can be induced by;
- Scratching the vessel
- Adding some seed crystals to the solution.
Hence, when you take a metal spatula and scratch the side of the glass vessel that contains this cooled solution, and crystals start to appear, crystallization has just occurred.

I think the answer is solvent but i'm not very sure.
<u>Answer:</u> The correct answer is Option d.
<u>Explanation:</u>
Temperature is defined as measure of warmth and coldness of a substance in reference to some standard value. It is expressed in Kelvins.
Kilogram is the S.I. uni of Mass.
Liter is the S.I. unit of Volume.
Meter is the S.I. unit of Length.
Temperature can be expressed in degree Celsius and degree Fahrenheit.
Hence, the correct answer is Option d.
68 kg. There are 58 kg salt in 500 gal seawater.
<em>Step 1.</em> Convert gallons to litres
1 US gal = 3.79 L (1 Imp gal = 4.55 L)
<em>Step 2</em>. Find the volume of the seawater
Volume = 500 gal × (3.79 L/1 gal) = 1895 L
<em>Step 3</em>. Find the mass of the seawater
Mass = 1895 L × (1.025 kg/1 L) = 1942 kg
<em>Step 4</em>. Find the mass of the salt
Mass of salt = 1942 kg seawater × (3.5 kg salt/100 kg seawater) = 68 kg salt
