It is a good idea because when mercury heats up, the molecules spread farther apart. Therefore, making them look to have expanded. Thermometers that are digital use a sensor to, as you would say feel the temperature around it.
it works very well for atoms with only one electron, like H or He+, but not at all for multi-electron atoms.Bohr's model breaks down when applied to multi-electron atoms.
Answer:
13) Carbon Dioxide and water
Explanation:
The fact is that during photosynthesis, Carbon Dioxide is needed by green plants to manufacture their food and water is also needed but also chloroplast which contained chlorophyll is also needed
hence, the options are somehow confusing
14) perhaps it should be all of the above
Archimedes' principle allows us to find that the reasons why the thrust is not written when a body is in the air is:
- The thrust of air is about 800 times less than the thrust of a fluid
- In general the other forces (weight, tension) are much greater than thrust
Archimedes' principle establishes that the thrust is equal to the weight of the dislodged liquid (fluid)
B = ρ g V
Where B is the thrust, ρ and V the density and volume of the fluid, respectively, g the acceleration due to gravity.
In the attachment you have a diagram of a system in equilibrium in air and water, we can see that in the two cases for a system in equilibrium
B -W = 0
B = W
Let's find the value of the thrust in each case and compare
Used the density
Suppose that the volume of the two bodies is the same
r
We can see that the thrust in air or other gas is about 800 times less than the thrust in liquids. This is the reason that in many problems the thrust is not written when the body is in the air.
In conclusion, using Archimedes' principle, we find that the reason why the healed thrust is not written for a body is in the air is:
- The thrust of air is about 800 times less than the thrust of a fluid
- In general the other forces (weight, tension) are much greater than thrust

A monobromination reaction of an alkane involves an alkane and bromine. The position of the hydrogen atom that will be substituted by the bromine free radical will depend on the order of the alkane. The bromine will attach to the carbon that has the most substituents.
