Why should you never heat a flask when sealed with a cork?
increased pressure and temperature
Why should an aerosol can never be thrown into a fire?
You should never throw an aerosol can onto a fire or leave it in direct sunlight - even if it is empty. This is because the pressure will build so up so much that the can will burst (and explode if there is a naked flame nearby). There are two reasons for the pressure going up:the gas pressure increasesmore of the liquefied propellant turns into a gas
Why did your thermometer never hit 100 degrees Celsius when boiled?
You are probably above sea level so that the atmospheric pressure is lower than sea level pressure. Water boils at lower temperatures as the pressure is lowered. The other possibility is that the thermometer is not calibrated correctly, but I'd go with the atmospheric pressure is below sea level pressure.
Why should an absorbance level not exceed a value of 1?
Since the absorbance level is actually just a fraction of radiation absorbed at a given wavelength, it should never rise above %100.
Explain why an aerosol can should never be thrown into a fireplace or incinerator?
It will explode with considerable force, causing death and injury. The pressure in the sealed can rises when heated. When it is high enough, the can ruptures.
When welding with a 3 tip what should the oxygen and acetylene be set at?
If you set your tanks to about 5 psi and 5psi, you should not have to change the pressure, instead simply adjust the knobs on the torch to give more of each gas. If this still is a problem, try 7-9 psi for each. NEVER NEVER NEVER go above 12 for acetylene, it is unstable at 15, best to not get close...
How do you know that oxy-acetylene hoses are flame retardant?
They aren't, which is why you should never have them laying near your work area. What I do is drape them over my shoulder and keep them behind me.
What should you never do when stretching?
You should never bounce. You should stop if you feel pain. Don't hold your breath.
Where should you never place electrical cords?
all the above

What should you talk and do with him when your alone?
What you do and talk about with him when you two are alone depends on how comfortable you are. He should never pressure you into doing or saying something that you are not comfortable with.
Should you go to the Er if your blood pressure is 169over 118 during the day?
YES. You should definatly go to the ER. That is extremely high. It should NEVER be that high.
Should parents put pressure on their children?
no never Well a little so they do things they have to do like homework for instance.
Is the notary stamp above the signature?
The appropriate location for the notary stamp is to the side or immediately underneath the notary's signature. The stamp should never be above the signature.
