What is the definition of nonpolar?

• No separation of charge
• A substance that does not have an affinity for water
• A substance that has an affinity for water
• Unequal distribution of charges; polar molecules typically dissolve in water because water is also polar

• The smallest part of an element that still has the properties of that element
• The most basic unit of life
• Anything that has mass and occupies space

What is the definition of hydrophobic?

• A measure of how difficult it is to stretch or break the surface of a liquid
• The most basic unit of life
• A substance that does not have an affinity for water
• A substance that has an affinity for water

What is the definition of a solution?

• Anything that has mass and occupies space
• A uniform homogenous mixture of two or more substances
• The smallest part of an element that still has the properties of that element
• The most basic unit of life

• Atom, molecule, cell, tissue, organ, organism

What is the definition of a solvent?

• Anything that has mass and occupies space
• What gets dissolved in a solution
• What does the dissolving in a solution
• The smallest part of an element that still has the properties of that element

What is the definition of an atom?

• A measure of how difficult it is to stretch or break the surface of a liquid

What is the definition of surface tension?

• The most basic unit of life
• Anything that has mass and occupies space
• The smallest part of an element that still has the properties of that element
• A measure of how difficult it is to stretch or break the surface of a liquid

What is the definition of a solute?
