What is the definition of a solid?

Select the correct definition for surface tension.

• The result of an inward pull among the molecules of a liquid that brings the molecules on the surface closer together, causing the surface to act as if it has a thin skin
• A state of matter that has no definite shape or volume.
• A state of matter that has a definite shape and a definite volume.
• A liquids resistance to flowing.
• A state of matter that has no definite shape but has a definite volume.

Type the definition for liquid.

What is the definition of thermal energy?

• The total kinetic and potential energy of all the particles of an object
• The temperature at which a liquid freezes. 0 C
• The change in state from a liquid to a gas.
• The temperature at which a substance changes from a solid to a liquid; the same as the freezing point, or temperature at which a liquid changes to a solid
• The temperature at which a liquid boils, 100 C
