Bismuth, having a relatively low melting point at 520.7 F (271.5 C), can be melted using readily available household heat sources like a stove top.
In terms of workability, Bismuth is very similar to Copper, though a bit more brittle.

Because of it is very workable when molten, is generally considered non-toxic, and has a low melting temperature, Bismuth casting is not difficult at all.

Bismuth does oxidize very quickly, leaving a usually glossy red to blue coating. While oxidizing, it may form a thin layer of weak acid on the surface so casting in ferrous molds is possible but will result in loss of some of the Bismuth as it bonds to the surface of the ferrous mold.

To put a flashlight together, first gather all the necessary components such as the flashlight body, batteries, LED bulb, reflector, switch, and lens. Then, assemble the components in the correct order following the manufacturer's instructions or a DIY guide.

As bullion, pretty much nothing. But it is probably a commemorative of some sort which may give it some value to someone whose collection consists of things related to the subject it commemorates.

The guard cells synthesize glucose through photosynthesis in the presence of light. as glucose accumulates, osmotic pressure increases and this enables them to draw water from adjacent epidermal cells by osmosis. this makes the guard cells turgid and the stomata opens. at night, there is no photosynthesis and therefore glucose levels go down leading to lowering of osmotic pressure. guard cells lose turgidity and become flaccid and therefore stomata closes. Am sure you can derive your answer from this.

A mass of one kilogram weighs one kilogram on Earth, as weight is the force exerted on an object due to gravity.

As I recall my physics from many years ago, a falling body accelerates at 36 feet per second squared. After one second a body has fallen 36 feet. To convert to Miles Per hour I use the following: 36 x 60 seconds x 60 minutes divided by 5280 feet per mile, or 36 x 60 x 60 / 5280 = 24.545 Miles per hour.

Suggest double checking with a local school physics teacher or a loaca library reference librarian.

In fair to good condition: $80-120. There is not strong interest in this gun by collectors, but it is a fine little plinker. Nickel plating--depending upon the condition--may actually detract from the value.

A scale model of Earth is a proportional representation of the planet in a smaller size. It can be used for educational purposes, scientific research, or as a visual aid to help understand the Earth's structure and features. Scale models can vary in size and detail, depending on the specific purpose for which they are created.

People are greedy because they feel like everything is for them. They don't care for animals or for any other living creatures. Have you noticed what is on the back of some trucks? Something against wildlife of course. When someone comes to a estate to get rid of woodchucks, they don't capture them and let them go back into the wilderness. You want to know why? Because people are so greedy there isn't any wildlife left. A theory of how the world will end is that greedy people will kill out all the animals and then everyone will have to become vegetarians and then there won't be enough food to go around and everyone will die. Why? Because people are greedy. Because they feel like it ok !!

To calculate pKa, you can use the Henderson-Hasselbalch equation: pKa = pH + log([A−]/[HA]), where [A−] is the concentration of the conjugate base and [HA] is the concentration of the acid. Alternatively, you can look up the pKa value in a table or use a chemical database.

mass or volume. Sound is a type of energy that travels through a medium, such as air or water, in the form of waves. It does not have a physical substance or matter.
