Which statement is correct about the unknown substance?
A. Its melting point is 17 °C.
B. Its melting point is 15 °C.
C. The substance sublimes at 15 °C.
D. The substance exists as a gas at 17 °C.
It is given that the unknown substance is solid at 15 degree celsius. When further heated then heat energy breaks the bond between molecules of the solid.
As a result, temperature remains constant until all the bonds are broken down to convert the solid into liquid.
Hence, the constant 17 degree celsius temperature shows that the solid is melting and after it completely melts then it converts into liquid at 23 degree celsius.
Thus, we can conclude that the statement its melting point is 17 °C, is correct about the unknown substance.
The reason why is because the temperature in degrees Celsius for it to turn into a solid is 23 degrees and it isn't quite 23 degrees but not so little it will barely do anything to it at all.
By soil parent material type is understoodunconsolidated deposits (regolith) found on the bedrock. Most Soil parent materials are made up from weathered and disintegrated rock material.
<span>The main job of the large intestine is to absorb water from the undigested mass. This keeps large amounts of water in your body and helps maintain homeostasis.</span>
The movement of water molecules in and out of a cell is called osmosis.
Osmosis, or the diffusion of water molecules, is when water molecules flow in or out of a cell from high to low concentrations (down their concentration gradient). The ultimate goal of osmosis is to establish equilibrium between the cell and its outer environment.
The common hepatic duct is formed by the union of the right and left hepatic ducts emerging out from the right lobe of the liver.
The right hepatic duct is responsible for draining bile from the right half of the body whereas the left hepatic duct drains it from the left side of the body.
At the junction of the right and left hepatic duct, the common hepatic duct gets formed which then joins the cystic duct and then the common bile duct is formed.
