# Properties of Matter Worksheets

## Properties of Matter Worksheets for Grade 7

Properties of matter refer to the characteristics and attributes that can be used to describe and identify different substances. These properties can be observed or measured and provide valuable information about the nature and behavior of matter. The properties of matter can be broadly categorized into two main types: physical properties and chemical properties.

Understanding the properties of matter is essential to unraveling the mysteries of the physical world around us.Our collection of worksheets is designed to cater specifically to grade 7 science curriculum standards, ensuring they align with your educational needs.

### Volume

A three-dimensional measure of the size of a body or region.

### Meniscus

It is the curve at a liquid’s surface by which we measure the volume of the given liquid.

### Weight

A measure of the gravitational force exerted on an object; its value can change with the location of the object in the universe.

### Inertia

Any objects’ tendency to resist from being moved or, even though it is moving, to resist a change in speed or direction to the point where an outside force acts on the object.

Atoms It is the smallest unit of an element that maintains the properties of the elements.

Metals are shiny, good conductors of heat and current, malleable and ductile.

Nonmetals are dull, bad conductors, brittle.

Metalloids are mix of metal and non metal properties.

Atoms can be further divided into smaller parts.

There are three main parts of an atom: the protons, neutrons and electrons. The protons and neutrons make up the middle part of the atom called the nucleus. The electrons are outside of the nucleus of the atom.

### What are the two types of properties of matter?

Properties of matter can be divided in two ways – extensive/intensive or physical/chemical.

### What are the properties of a solid, liquid and a gas?

We know that liquid has no definite shape and it takes the shape of the container in which it is poured. Liquid has a definite volume. When a liquid is heated, it changes to gaseous form.

In solids, molecules are arranged close to each other in a way where they cannot move but only vibrate.

In liquids, molecules are arranged in a way so that they can move freely. So, definitely molecules are loosely arranged in liquids than in solids.

In gases, molecules are arranged in a loose manner such that they can easily move quickly in all directions.

##### What are the properties of matter?

Properties of matter are the characteristics and attributes that describe different substances. They can be classified into physical properties and chemical properties. Physical properties include characteristics like color, texture, density, and boiling point, while chemical properties describe how matter behaves in the presence of other substances and involve its ability to undergo chemical reactions.

##### Why are properties of matter important?

Properties of matter are important because they help us identify, classify, and understand different substances. They provide valuable information about how matter behaves under various conditions and allow scientists to study and manipulate materials for practical applications in fields such as engineering, medicine, and environmental science.

##### How are physical properties of matter different from chemical properties?

Physical properties of matter describe observable characteristics that can be measured without changing the substance’s chemical composition. Chemical properties, on the other hand, describe how matter interacts with other substances and involve its ability to undergo chemical reactions, which result in the formation of new substances with different properties.

##### Can properties of matter change?

Properties of matter can change under different conditions. For example, physical properties like melting point and boiling point can vary with changes in temperature and pressure. Chemical properties can also change when matter undergoes chemical reactions or transformations.
