A vacuum flask, or thermos, does not allow heat transfer by any of the three ways that heat can travel. The silver coating on the inner bottle prevents heat transfer by radiation, and the vacuum between its double wall prevents heat moving by convection.

Soil erosion is defined as the wearing away of topsoil. Topsoil is the top layer of soil and is the most fertile because it contains the most organic, nutrient-rich materials. One of the main causes of soil erosion is water erosion, which is the loss of topsoil due to water.Rainfall and the surface runoff which may result from rainfall, produces four main types of soil erosion: splash erosion, sheet erosion, rill erosion, and gully erosion.

Ruminant Artiodactyl (including cattle, deer, and their relatives) are unable to digest plant material directly, because they lack enzymes to break down cellulose in the cell walls. Digestion in ruminants occurs sequentially in a four-chambered stomach. Plant material is initially taken into the Rumen, where it is processed mechanically and exposed to bacteria then can break down cellulose .The Reticulum allows the animal to regurgitate & reprocess particulate matter ("chew its cud"). More finely-divided food is then passed to the Omasum, for further mechanical processing. The mass is finally passed to the true stomach, the Abomasum, where the digestive enzyme lysozyme breaks down the bacteria so as to release nutrients.

Key Differences Between Physical Change and Chemical Change
The points given below discusses significant differences between physical change and chemical change
- A change in which the molecules are rearranged, but their internal composition remains same is called Physical Change. A process in which the substance transforms into a new substance, having a different chemical composition, it is known as Chemical Change.
- Some common examples of physical change vaporisation, condensation, freezing/melting/boiling of water. On the contrary, the examples of chemical change are combustion, metabolism, cooking of egg, etc.
- Physical change is a temporary; they are easily reversible. As against this, the chemical change is permanent in nature, i.e. they cannot be reversed, even by reversing conditions.
- In the physical change, only the form of the substance is changed, but no new product is formed. On the other hand, when there is a chemical reaction, a completely different product is formed, whose properties are completely different from that of the reacting substances.
- In a physical change, the original matter can be recovered, by simple physical methods. As opposed, in chemical change the original matter no longer exist, and so it cannot be recovered.
- In the physical change, change in the physical attributes of the substance is observed, such as shape, size, appearance, texture, odour, density and so on. Conversely, chemical change involves the change in chemical properties of the substance, i.e. change in its chemical nature.
- In the physical change, no or very little amount of energy is absorbed or given out as heat, light or sound energy. Unlike chemical change, wherein enormous energy is absorbed or given out as heat, light or sound energy.
