What is the use of the glass rod in transferring liquid reagents?
The glass stirring rod is used in liquid transfer in order to prevent spillage and facilitate the maximum amount of liquid transferred from one vessel to the next. The liquid's surface tension, or the fact that like molecules will tend to "stick" to each other make the liquid transfer virtually seamless from the lip of one vessel, to the stirring rod, and into the receiving vessel.
What is meniscus level?
When a liquid is held in a vessel, the water adheres to the side of the vessel. So when the amount of liquid held by the vessel is less than the full amount the vessel will hold, the liquid level rises where it touches the vessel. It "sticks" to the side of the vessel hard enough to be above the top of the liquid. This is called a negative meniscus. When the level of the liquid is higher than the top of the vessel (but doesn't overflow the top due to the surface tension of the liquid), then there is a positive meniscus.
How do you calculate the amount of gas required to raise the pressure of a closed vessel to a known value?
If you know the temperature, pressure and volume of the vessel, you can calculate the amount of moles through the Ideal gas law. PV = nRT That is assuming you have ideal conditions. If not, a variance of the ideal gas law can be used in order to get the moles of your gas.
Is a vessel a container?
Yes, a 'vessel' can be a container.
Why it is called as xylem vessel but not xylem cell?

When is a sail boat under sail the given way vessel when encountering a power driven vessel?

Which vessels are exempt from displaying validation decals in Maryland?
Non-motorized vessel under 16 feet in length
A vessel may not be operated on Washington waters if when measured from the shore it produces a noise level over what decibel level?
A vessel may not be operated on Washington waters if, when measured from the shore, it produces a noise level over 75 decibels.
If your vessel does not have a capacity plate what is the rule of thumb for estimating the maximum number of persons you should carry?
vessel length (ft.) multiplied by vessel width (ft.) divided by 15
In North Dakota when operating a personal watercraft PWC within 100 feet or less of an anchored or non-motorized vessel what must be done?
Operate at no wake speed
What is the rule of thumb for estimating the maximum number of persons you should carry on a boat?
vessel length times vessel width divided by 15
What is the maximum speed you may operate a vessel with in 100 feet of a dock?
6 knots
What is the maximum length of a scramble net for a ship?
The maximum length necessary to reach from the deck of the ship to the waterline when the vessel is in a fully unladen condition.
What should a sailing vessel operator do when approaching a PWC head on?
A sailing vessel operator should sound a blast on the horn when approaching a PWC head on. However, it is up to the operator of the motorized craft, in this case the PWC, to take evasive action.
