During thermal expansion what happens to the density of a substance?
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.
When an object has changed shape state and volume and density and no new substance is formed what type of change is it?
This is a physical change.
Gases do not have definite?
Gases are highly compressible. So they don't have definite volume and pressure. As volume is reduced for a given mass pressure increases. Also as temperature changes then at constant volume pressure changes considerably. Same way for a constant pressure temperature change brings a change in the volume. Moreover gasses do not have a free surface.
What is a substance which has a volume of 1 ml?
Any substance can have a volume of 1cm3, depending on its size (referring to density). For example, 1g of water would have a volume of 1cm3, while 0.8g of ethanol would have the same volume.A substance which has a volume of 1 cm3 is a substance that has a volume of 1 ml. Many substances can have a volume of 1 ml.
To measure how much stuff is a specified volume of a substance scientist use?
They would use density to measure the volume of a substance :)
What properties of a substance does not change when the amount of the substance changes 1 mass 2 volume 3 temperature?
The mass of a substance does not change when the amount of the substance changes. The temperature of a substance does not change when the amount of the substance changes. However, the volume of a substance may change when the amount of the substance changes, depending on the conditions.
How can you tell in an experiment if there has been an energy change?
You can tell if there has been an energy change in an experiment by measuring the temperature change, observing changes in physical states (solid, liquid, gas), or detecting changes in the color or luminosity of a substance. Additionally, you can also measure changes in the volume of a substance or track any work done by or on the system.
How will the mass of a pure substance be affected when the volume is increased?
The mass of a pure substance will remain constant even if the volume is increased. The mass of a substance is an intrinsic property that does not change with changes in volume.
When you heat a cool substance does the mass or volume change?
When you heat a cool substance, typically the volume increases while the mass stays constant. This is because heating usually causes the particles in the substance to move faster, spreading out and occupying more space. However, the actual mass of the substance remains the same during this process.
What state of matter does not change in volume?
A solid is a state of matter that does not change in volume because the particles are closely packed together and have fixed positions.
Is the specific gravity of substance the same when the substance is in the solid state?
No. Roughly speaking, "specific gravity" is equivalent to density, i.e., mass divided by volume. If a substance changes its state, its volume will change, but its mass won't change - therefore, the density - the result of the division - will also change.
How is the density of a pure substance affected if the mass and or volume are changed?
The density of a pure substance remains constant regardless of changes in mass or volume. Density is a physical property that is inherent to a substance and is calculated as mass divided by volume. As long as the substance remains the same, the density will not change.
Are changes in the state of matter are physical chemical or neither?
Changes in the state of matter are physical because they involve a change in the physical properties of a substance, such as its shape, volume, or density, without altering its chemical composition. Examples include melting, freezing, evaporation, and condensation.
What are two physical changes that cooling a hot substance may resuit in?
Cooling a hot substance may result in the molecules slowing down, leading to a decrease in volume and contraction of the substance. Additionally, cooling can cause a phase change, such as from a liquid to a solid, as the substance reaches its freezing point.
Does a change of state affect the objects volume?
Yes, a change of state can affect an object's volume. For example, when a substance changes from a solid to a liquid or a gas, its volume can increase. This change in volume is due to the different arrangements of particles in each state.
it becomes harder to change into a state that needs more volume?
When a substance changes its state of matter (e.g., from solid to liquid or from liquid to gas), the volume it occupies can change significantly. Generally, changing into a state that requires more volume often involves the substance expanding. For example, when a substance changes from a solid to a liquid or a liquid to a gas, its particles gain more kinetic energy and move more freely, leading to an increase in volume. When water turns into steam (a gaseous state), it expands significantly compared to its liquid state. Conversely, when a substance changes to a state that requires less volume, it often contracts or condenses. For example, when steam condenses back into liquid water, it occupies less space. It's important to note that the behavior of a substance during state changes depends on factors such as temperature and pressure. Additionally, not all substances behave the same way during state changes. Different substances have different properties that influence how they change states and how their volumes are affected.
How can you change density of a substance?
You can change the density of a substance by changing its volume. Density is equivalent to mass over volume. So changing the volume affects density.
