What else can I help you with?
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.
What happens when a pure substance undergoes a chemical change?
when a pure substance undergoes a chemical change it is no longer that same substance. A chemical change changes the identity of the substance. Hope i helped
What happens to the distance between particles of a substance as it changes from a liquid to a gas?
The distance between particles increases as a substance changes from a liquid to a gas. In the gas phase, particles are spread far apart and move freely, leading to higher distances between them compared to the closer arrangement in the liquid phase.
What happens to the volume when heat is added?
When heat is added to a substance, its particles gain energy and move more vigorously, causing the substance to expand and increase in volume. This is because the increased energy disrupts the forces holding the particles together, allowing them to spread out more.
When a substance is heated what happens in mass volume and weight?
When a substance is heated, its mass remains constant because mass is a measure of the amount of matter present, which does not change during a physical change like heating. Volume may expand due to thermal expansion, where the particles move farther apart. Weight may appear to change due to differences in gravitational force, but the actual mass remains the same.
What happens when a substance undergoes thermal expansion?
When a substance undergoes thermal expansion, its particles gain energy and move farther apart, causing the substance to increase in volume. This increase in volume is due to the increased average kinetic energy of the particles, leading to the substance taking up more space.
What happens to particle movement as heat is added?
As heat is added to a substance, the particles in the substance gain kinetic energy and move faster. This increased movement causes the particles to vibrate and collide more frequently, leading to an expansion of the substance.
What happens to a particle of a substance when it expands?
individual particles do not expand, when a substance expands it is the dead space between the particles that expands and the particles begin to move around (assuming the substance was solid to begin with). If a particle did expand it would loose cohesion and break apart (possibly creating an atomic reaction depending on how it was expanded)

What happens to particles when boiled?
Boiling occurs when the intermolecular forces holding a substance in the liquid state become overwhelmed and allow the particles to separate into the gaseous state. Particles in the gaseous state are roughly 2000 times farther apart than in the liquid state, which causes expansion of the substance in its gaseous form.
What happens to particle size when a substance undergoes physical change?
In general, the particle size remains the same during a physical change. The arrangement or organization of the particles may change, but the individual particles themselves do not break down or change in size.
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.
What happens when to particles of a substance when it condenses?
Particle Movement decreases.
When a substance is heated what happens to kinetic energy of particles?
When a substance is heated, the kinetic energy of its particles increases. This leads to the particles moving faster and colliding more frequently with each other and the container they are in.
What happens to the mass of a substance as the temperature is increased?
The temperature of a substance has no effect on its mass.UNLESS ... part of it evaporates and blows away, or melts in a puddle and runs off the edge of the table.As long as all of the substance stays there, its mass doesn't change, no matter how hot or cold it gets.
What phase change happens when something dissolves?
Dissolving a substance does not involve a phase change.
