Is this an organic material?Danilo Boskovic said:By slightly, i ment relatively slightly. The thing is i can not lose more of the substance as i only have a limited source of the plant as its season has passed.
Danilo Boskovic said:unknow solid, unknown properties
Well which is it? Is the substance unknown, or do you know what it is because you know what plant you ground up?Danilo Boskovic said:i only have a limited source of the plant as its season has passed
Low pressure refers to a decrease in the amount of atmospheric pressure in a given area. When solids are exposed to low pressure, the molecules that make up the solid are pushed further apart, causing the solid to expand in volume. This expansion can lead to changes in the physical properties of the solid.
Low pressure can cause a decrease in the strength of solids. As the molecules in the solid are pushed further apart, the bonds between them become weaker, resulting in a decrease in the overall strength of the solid. This can make the solid more susceptible to breaking or deforming under stress.
Yes, low pressure can cause solids to change state. When exposed to low pressure, some solids can undergo a process called sublimation, where they transition directly from a solid to a gas without passing through a liquid state. This is because the decreased pressure causes the molecules in the solid to have more energy and break free from their solid state.
Low pressure can lower the melting point of solids. This is because at lower pressures, the molecules in the solid have more energy and can move more freely, making it easier for them to overcome the attractive forces holding them together. This results in a lower amount of heat needed to melt the solid.
Yes, there are various practical applications of this phenomenon. For example, low pressure can be used to freeze-dry food or preserve biological samples. It is also used in the production of materials such as aerogels, which have unique properties due to their low-density structure. Additionally, low pressure is important in understanding the behavior of materials in outer space, where atmospheric pressure is significantly lower than on Earth.
