Using a dry bulb thermometer in my Vacuum chamber I observed a large Temp differential, Why?

Because the release of pressure (or pulling a vacuum)is an endothermic process. This would drop the temperature inside your vacuum chamber. This is a law of physics utilized by refrigeration equipment which basically uses  compression of refrigerant and subsequent release of pressure to cause cooling.

Lower temperatures might stabilize the bed. A broader surface of measuring probe (perhaps spring actuated?) might get a more average reading of bed height. It might be a little unphesiable currently, but lazer telemetry might solve your problem entirely.

You guys are both right--good answers.  Junction temperature also can affect the voltage drop.

Sounds like there is a short somewhere.  Look for damaged or loose wiring.  Look at battery terminals -- anything touching them that should not be.  Are all the wires adequately insulated?

Make sure that ventilation holes are free of dust. You can use compressed air to blow out the dust gathered in the heatsink.

Since you mean the light bulb is good, then a whoosh of the gas Argon will come out of the bulb.  If you were careful, you could do this without breaking the bulb.\n\nDon't try to do it unless you wear protective eyewear and hand protection!  The bulb is under some pressure; it is not a vacuum.

try\nhttp://www.dir.ca.gov/title8/2395_42.html\nsection b\n\nGrounds are also tied to the cold water pipes and gas pipes.\nmake sure all circuits are dry and checked with a insulation resistor tester (megger).Readings above 2 Mega Ohms should be OK.

You have it backward.  The temperature is dependent on some function of time not the other way around.

I only had time to do the first one, btu the answer is \ne-2.  Check your email for the work.

A sharp increase in temperature.

This kind of depends on the other conditions of your experiment.  By Boyle's law, PV=nRT, or pressure times volume = number of moles of gas times a constant times temperature.  Since your pressure goes up, the only way to keep temperature constant is to reduce the volume of your container by half.  Is that the condition of the experiment?  Your gas is in a piston chamber of some sort?  Generally, compressing a gas increases its temperature, so I suppose if you did this, you could measure the temperature beforehand, compress the gas and then wait until the gas cooled back down to the same temperature.\n\nIn any event, since temperature is simply the measure of the average kinetic energy of all the particles in a system, since kinetic energy itself is calclulated by knowing velocity and mass and the mass hasn't changed, at the same temperature, the gas molecules have the same average kinetic energy and therefore the same velocity, and since you don't specifically care WHICH direction they're travelling in, they are at the same speed.

The resistance of the filament of the lamp varies with temperature. When the filament is at room temperature the resistance is much lower than when it is white hot. \n\nCurrent = V/R. If the voltage is constant and the resistance increases, the current decreases.

Does it have to be a material? the best solution for this would be to have 2 cans one just inside the other with a compleat vacume between them, as there is no air to transmit the heat between them the liquid inside wont change tempreture.\n\nthis is the principle of a thermos flask,\n\nif you need an actual material, somthing that would trap air to stop it from moving and spreading the heat such as glass fiber like you might have in your loft\n\nhope this helps

something really harsh like paint stripper would have an effect as its quie volatile. if you can pour a flammable liquid into the tube such as petrol etc this will light from a distance but be super careful

check out event log for finding the exact problem. it's greatly exprected that the problem is due to overheating.

Perhaps a light wouldnt work under the extreme conditions of a freezer :D
