When a substance is heated it can result to a rise in?
When a substance is heated, it can result in a rise in temperature, causing the molecules to move faster and increase their kinetic energy. This increase in kinetic energy may lead to changes in the state of matter, such as melting or boiling.
What happens to density of a solid substance when it is cut in half?
The density of the solid substance remains unchanged when it is cut in half. The mass and volume are both halved, which means the ratio of mass to volume, i.e., density, stays the same.
What will the mass of the air when it expand?
Sucker how do I know that what I asked right
How do you calculate the density of a substance?
The density of a substance is calculated by dividing its mass by its volume. The formula for density is: Density = Mass / Volume. This calculation gives you a measure of how tightly packed the molecules are in a given sample of the substance.
What happens if a substance of unknown composition is heated in a sealed container As a result the mass of the container and its contents?
If a substance of unknown composition is heated in an open container will Its mass will stay the same as a result the mass of the container and its contents decreases. A substance of an unknown composition is heated in a sealed container the mass of the container and its content remains the same.
What happens to a substance or object when it is heated?
It expands.
When a substance evaporates what happens to its mass?
Its mass is unchanged.
What happens to the mass when a substance when rusting happens?
When rusting occurs the mass of the substance increases since the rusting material reacts with the oxygen in air
What happens when density expands?
density is a measure of mass that is contained in a unit of volume for a particular substance. it increases it cannot expand if we say that density is increasing it means that either mass has increased or volume has decreased like on cooling volume decreases. on mixing(chemically or dissolving) mass increases.
When a substance freezes what happens to the mass?
When a substance freezes, the mass remains the same. Freezing involves a phase change from liquid to solid, where the molecules arrange themselves into a more ordered structure, but the actual amount of matter (mass) stays constant.
What happens to density during the heat expansion of a substance?
Think of of the expanding substance as a box full of marbles. If it expands, they end up in a bigger space (in this case a bigger box). Because of that they have more room to move around and there will be less particles and less mass per cm2 which is what the density is.
When a substance is heated it can result to a rise in?
When a substance is heated, it can result in a rise in temperature, causing the molecules to move faster and increase their kinetic energy. This increase in kinetic energy may lead to changes in the state of matter, such as melting or boiling.
What substance expands when frozen?
water
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 density when you keep the volume the same and increase the mass of the substance?
When you keep the volume constant and increase the mass of a substance, the density of the substance will also increase. Density is calculated as mass divided by volume, so if volume stays the same and mass increases, density will increase as well.
What happens to density of a substance during thermal expansion?
Thermal expansion is the tendency of matter to change in volume in response to change in temperature. During thermal expansion, the density of a substance decreases as its volume increases. Volume is the space occupied by a body. So, when a substance expands on heating, it will occupy more space or will have more volume. But its mass does not change because the amount of matter contained in a body cannot change. Therefore, mass divided by increased volume gives a decreased density.
What happens to the mass of the volume is tripled?
If the volume is tripled, the mass will stay the same as long as the substance remains constant. Mass is an intrinsic property of matter and is not affected by the volume it occupies. The density of the substance will decrease as the volume increases.
