What is the effect on the volume of a substance when thermal energy is added?

Adding heat to something generally increases its volume. In rare cases, adding heat to something like ice may actually decrease its volume. The increase in volume of a heated gas is much more significant than the increase in volume when solids and liquids are heated.

∙ 15y agoWhen thermal energy is added to a substance, we say it is heated. For most substances, when they are heated, they expand and their volume increases. One exception is water ice, which expands as it freezes, and therefore contracts when heated near its melting/freezing point.

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.
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.
Substances expand when heated because the molecules?
According to the particle theory, particles move faster and further apart when exposed to higher temperatures. When a substance is heated, its particles acquire thermal energy. These energetic particles--which are constantly vibrating, even in solid form--become very excited, and move around much more, therefore requiring more space. The substance begins to increase in volume, creating larger spaces in between its molecules to accommodate the high-energy movement. This can also cause a change in state. Particles of substance in a solid state: vibrating slightly, densely packed together, little space between molecules. Compare to, Particles of substance in a gaseous state: vibrating excitedly, larger spaces in between molecules, easily compressible (due to empty spaces) If you were to cool a substance in gaseous form, the particles would begin to lose their thermal energy, and eventually change into a liquid state.
What is thermal expansion?
Thermal expansion is the physical change of size of something owing to higher thermal energy of the object. Heat (thermal energy) causes increased atomic motion in materials, and this change in the kinetic energy of the atoms and molecules of a material will cause it to increase in volume. It is a physical characteristic of matter (as opposed to a chemical one), and it is pretty much true across the board. No, ice does not expand when it turns to water, and there are a couple of other exceptions, but, in general, when we heat things, they increase in volume. So the density will decrease but mass remains the same. As in the density formulae, Density= Mass over Volume. When mass do not change and volume increases, it is obvious that it had density to be lower.
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 :)
How is temperature and thermal energy different?
Temperature is when the heat measures the average of the kinetic energy Thermal is averged together with kinetic engery, and all the others, to make thermal energy
What is thermal expanison?
Thermal Expansion is the increase in volume of a substance due to an increase in temperature.
What is the increase in volume of a substance due to an increase in temperature?
thermal expansion
What is the increase of the volume of a substance by the increase of temperature called?
This increase of volume is called expansion
As the temperature of a substance increases its volume tends to increase due to what?
thermal expansion
Why does mercuri expand when heated?
When thermal energy is added to a substance, the molecular movement increases. Because they are moving around, they need more space, which is provided by occupying a larger volume.

What is an increase in the size of a substance in response to an increase in the substance's temperature?
boyles law describes how when temperature rises the volume rises
When a substance is heated what happens in mass volume and weight?
Both the mass and weight remain unchanged. However; generally; the volume increases due to the thermal expansion of the substance when heated up.
