When a substance is heated, the kinetic energy of its molecules increases, causing them to move faster and further apart. This results in an expansion of the substance's volume. Conversely, when a substance is cooled, the molecules slow down and move closer together, causing the substance to contract.

Why does the substance in the column of the thermometer go up when it is heated?
When the substance in the column of a thermometer is heated, its temperature increases. As the temperature increases, the particles in the substance move more energetically and spread out, causing the substance to expand and rise up the column. This expansion is what causes the fluid to rise and indicate a higher temperature reading on the thermometer.
What is an increase in volume that occurs when heat is added to a substance called?
An increase in volume that occurs when heat is added to a substance is called thermal expansion. This happens because the particles within the substance gain kinetic energy and move further apart, causing the substance to expand.
When a substance expands do the particles get bigger?
When a substance expands, the particles themselves do not get bigger. Instead, they move further apart from each other, creating more space between them, which leads to the expansion of the substance.
What substance expand to fill the entire volume of its container?
A gas can expand to fill the entire volume of its container because the particles are not confined and can move freely. When a gas is placed in a container, it will fill the entire space available to it.
What is a substance that causes pollution called?
A substance that causes pollution is called a pollutant. Pollutants can be in the form of chemicals, gases, or particles that are harmful to the environment and human health.
When substance are heated they?
They expand
What is a substance that does not have shape or volume but can expand and take up space?
A gas is a substance that does not have a fixed shape or volume. It can expand to fill the space available to it.
As a substance changes from a liquid to a gas the space between its particles?
increases, as the particles gain energy and move farther apart. This causes the substance to expand in volume as it transitions from a liquid to a gas.
What are the causes of stomach expand?
.eating too much will make your stomache expand
What causes substances when heated to splatter?
When a substance is heated, the molecules within it gain energy and move more rapidly, causing the substance to expand and potentially splatter. If the substance contains water or other liquids, heating can generate steam, leading to rapid expansion and splattering. Additionally, the presence of air or gas pockets within the substance can also contribute to splattering when heated.
Do all gases expand the same amount?
no, cuz there is a thing called the expansivity of a substance that tells us how much a particular substance will expand over 1 degree change in temprature
How air heat?
it causes air to expand
How does air heat?
it causes air to expand
What is the expansion meaning of eta?
That usually means that when you heat a substance, it will expand - its volume will increase.
Why does the matter expand when heated?
Heat energy causes all matter to expand, a reason for this strange occurrence is that when a particular substance receives heat whether it be through conduction, convection or radiation the atoms inside the substance become more energised therefor needing more space to move, they push the outside boundaries making the substance expand. If the substance receives an exceeding amount of heat energy it will change states of matter.
What happens to particles in a substance whe the sustance's temperature increase?
When the temperature of a substance increases, the particles within the substance gain energy and move more quickly. This increased movement causes the particles to spread out and the substance to expand. Additionally, the increased kinetic energy may lead to changes in the substance's state, such as melting or vaporization.
