Rylen Hugus 3.1

TermDefinition
Water A molecule made of two hydrogen atoms and one oxygen atom. It is essential for life and has unique properties.
Capillary action The ability of water to move upward through narrow spaces. It happens because of cohesion and adhesion
Cohesion Water molecules sticking to other water molecules. This creates surface tension.
Adhesion Water molecules sticking to other surfaces. It helps water climb materials like plant stems.
Polarity Water has a positive and negative end, like a magnet. This lets it dissolve many substances.
Transfer Moving something from one place to another. Energy, heat, or matter can all be transferred.
Energy The ability to do work or cause change. It exists in many forms like heat, light, or motion.
Atmosphere The layer of gases around Earth. It protects life and helps regulate temperature.
Hydrosphere All the water on Earth, including oceans, lakes, rivers, and groundwater.
Climate The long-term weather patterns of a region. It includes temperature, rainfall, and wind.
Convection Heat transfer through the movement of fluids like air or water. Warm materials rise and cool materials sink.
Freeze When a liquid turns into a solid. Water freezes at 0°C (32°F).
Dissolve When a substance breaks apart and mixes evenly into a liquid. The result is a solution.
Specific Heat Capacity The amount of heat needed to raise the temperature of a substance. Water has a high specific heat capacity, so it warms slowly.
Solid A state of matter with a fixed shape and volume.
Liquid A state of matter with a set volume but no fixed shape.
Gas A state of matter with no fixed shape or volume.
Solute The substance being dissolved in a solution.
Solvent The substance that does the dissolving. Water is the most common solvent.
Solution A mixture where the solute is evenly dissolved in the solvent.
Surface Tension The tight “skin” on the surface of water caused by cohesion.
Water Cycle The continuous movement of water through evaporation, condensation, and precipitation.
Kevin Scale A temperature scale starting at absolute zero. It is used mainly in science.
Absolute Scale A temperature scale that begins at absolute zero, where no heat energy remains.
Universal Solvent A nickname for water because it dissolves more substances than any other liquid.
Homogenous solution A mixture that is the same throughout, with evenly spread particles.
Examples Of Heterogenous Solutions Sand and water, oil and water, and cereal in milk.
Example Of Cohesion Water droplets sticking together on a window.
Example Of Adhesion Water sticking to the sides of a glass.
Example Of Surface Tension An insect standing on top of a pond.
Example Of Capillary Action Water climbing up a paper towel or up a plant’s stem.
