Match the term to the correct definition

Draggable item		Corresponding Item
matter		A combination of two or more substances that are NOT chemically combined
solute		a pure substance made of only one kind of atom and cannot be broken down
compound		Anything that has mass and takes up space
atom		A substance that is made of two or more elements that are chemically combined
solution		the smallest unit of most compounds
solvent		The part of a solution that does the dissolving
Polarity (polar)		the part of a solution that is being dissolved
element		A mixture that forms when one substance dissolves another
molecule		The smallest part of an element
mixture		means that the overall charge of a molecule is neutral even though opposite ends of the molecule have small opposite charges

Draggable item		Corresponding Item
hydrogen bond		the amount of heat needed to raise the temperature of 1 Kg of a substance 1degree Celcius
universal solvent		the force of attraction between water molecules and other water molecules
cohesion		a property of water that exists because ice is less dense than liquid water
surface tension		tightness across the surface of water.
Ice floats		the force of attraction between water molecules and other substances like glass.
slightly positive		the property of water that is due to the combined force of attraction - both cohesion and adhesion. (how water enters roots of a plant)
Heat capacity or specific heat		water is often called this because it dissolves so many substances.
capillary action		the bond created between water molecules
adhesion		the oxygen end of a water molecule
slightly negative		the hydrogen end of a water molecule
