Chemistry Lesson 2 Moving Matter

Definition of a liquid

• A liquid is a state of matter that is always in a gaseous form.
• A liquid is a state of matter that has both definite volume and shape.
• A liquid is a state of matter that has a definite shape but no definite volume.
• A liquid is a state of matter that has a definite volume but no definite shape.

Definition of a solid

• A solid is a three-dimensional object that has length, width, and height. It is characterized by having a definite shape and volume.
• A solid is a gas that expands to fill its container.
• A solid is a liquid that can change shape easily.
• A solid is a two-dimensional object with no volume.

Definition of a gas

• A gas has a fixed shape
• A gas is a solid state of matter
• A gas is a state of matter that has no fixed shape or volume.
• A gas has a fixed volume

What is the freezing point?

• The freezing point is the temperature at which a liquid turns into a solid.
• The freezing point is the temperature at which a liquid turns into a gas.
• The freezing point is the temperature at which a solid turns into a gas.
• The freezing point is the temperature at which a gas turns into a liquid.

What is the melting point?

• The melting point is the temperature at which a gas changes to a solid state.
• The melting point is the temperature at which a liquid changes to a gas state.
• The melting point is the temperature at which a solid substance changes to a liquid state.
• The melting point is the temperature at which a liquid changes to a solid state.

What is the temperature degree of both the melting and freezing point?

• The temperature of the melting point is higher than the freezing point.
• The temperature of both the melting and freezing point is the 32*.

• The temperature of the melting point is lower than the freezing point.
• The temperature of the melting point is not fixed.

How do scientists define liquids?

• Substances with definite shape and volume.
• Substances with no volume or shape.
• Substances that are always in gas form.
• Substances with definite volume but no definite shape.

What is an amorphous solid and a non-newtonian liquid?

• A solid without shape

• A liquid material with no defined shape
• A gas with high density
• A substance that conducts electricity

What is surface-tension?

• Surface tension is the tendency of liquid surfaces to shrink into the minimum surface area possible, acting as an invisible "skin'

• Surface tension is the force that causes liquids to evaporate quickly
• Surface tension is the tendency of liquid surfaces to increase in volume
• Surface tension is the expansion of liquid surfaces

What is the law of viscosity?

• The law of viscosity describes how thick or thin a fluid is based on its resistance to deformation by shear or tensile stress.
• The law of viscosity determines the color of a fluid based on its temperature
• The law of viscosity measures the smell of a fluid in relation to its density
• The law of viscosity calculates the sound produced by a fluid when poured
