States of Matter - Physical and Chemical Change

The three common states of matter are ________, ________, and ________.

(a)  

Answer explanation

The three common states of matter are solid, liquid, and gas. These states describe the distinct forms that different phases of matter take on, with solids having a fixed shape, liquids taking the shape of their container, and gases expanding to fill available space.

Matter cannot be created or destroyed according to the (a)   of matter.

Answer explanation

Matter cannot be created or destroyed according to the Law of Conservation of matter, which states that the total mass remains constant in a closed system.

(a)   is the process of changing from a solid to a liquid.

Answer explanation

Melting is the process of changing from a solid to a liquid. When a solid is heated, its particles gain energy and move apart, resulting in a liquid state.

The amount of matter in an object is its (a)   .

Answer explanation

The amount of matter in an object is referred to as its mass. Mass is a fundamental property that quantifies the amount of matter present, distinguishing it from weight, which is the force exerted by gravity on that mass.

The particles in a (a)   are tightly packed and do not move freely.

Answer explanation

The particles in a solid are tightly packed together, which restricts their movement. This is why solids maintain a definite shape and volume, unlike liquids and gases where particles can move more freely.

The process of a liquid becoming a gas is called (a)   .

Answer explanation

The process of a liquid becoming a gas is called evaporation. This occurs when molecules in the liquid gain enough energy to transition into the gas phase, typically at the surface of the liquid.

Rust forming on iron is an example of a (a)   change.

Answer explanation

Rust forming on iron is a chemical change because it involves a reaction between iron and oxygen, resulting in the formation of iron oxide (rust), which alters the chemical composition of the original material.

The state of matter with no definite shape or volume is (a)   .

Answer explanation

The state of matter with no definite shape or volume is gas. Gases expand to fill their container and do not have a fixed volume, unlike solids and liquids.

The state of matter with no definite shape or volume is (a)   .

Answer explanation

The state of matter with no definite shape or volume is a gas. Unlike solids, which have a fixed shape and volume, gases expand to fill their container, making them shape and volume flexible.

The amount of space an object occupies is its (a)   .

Answer explanation

The amount of space an object occupies is known as its volume. Volume measures how much three-dimensional space an object takes up, making 'Volume' the correct answer.
