Changes in state of matter in daily life ~ physics project
Click here for the index Changes in state of matter in daily life INTRODUCTION I am presenting this project assignment on the topic ............ In this project I have tried to give all the important things and information. Nearly every substance can exist as a solid, a liquid, or a gas. These are the three common states of matter. Whether a substance is a solid, a liquid, or a gas depends on its temperature and the pressure placed on it. Any change in phase is accompanied by the taking in or release of heat energy because, as change takes place, the attractive forces between molecules are being broken down or being formed. States of Matter It has been observed that matter exists in nature in different forms. Some substances are rigid and have a fixed shape like wood and stone; some substances can flow and take the shape of their container like water, while there are forms of matter that do not have definite shape or size such as air.
