If there is a question you are not asking it.
Now let us try to find out what the question might have been.
Assuming that both gases follow the ideal gas law, we have for both gases PV=nRT where P is the pressure, V the volume, T the absolute temperature, R the gas constant, and n the number of moles.
Let subscript _1 refer to the Helium gas and _2 to the Argon gas. You can write

  1. P_1*V_1=n_1*R*T_1
  2. P_2*V_2=n_2*R*T_2
Divide the left sides one by the other and do the same for the right sides. Since P_1=P_2 and T_1=T_2 there are cancellations and you are left with
That is all you can say: The ratio of the volumes is equal to the ratio of the numbers of moles.
Now using the molar masses of the gases (M_1=4 g, and M_2=40 g) you find n_1 is about 2 moles and n_2 is also about 2 moles. The conclusion is that the two balloons have approximately the same volume.
Note:You can use more accurate molar masses for the gases but that will not change the conclusion.
The question should have been: What is the ratio of the volumes of the balloons?

Hydrogen, helium and methane are gases on earth .why are these substances liquids on the gas giants

The surface below the point where their state changes to liquid or boiling point. Boiling Point Degrees above absolute zero: Helium - 4.2 Hydrogen - 20.2 and Methane - 111 degrees (At standard pressure- under pressure the boiling point rises - that is why propane tanks work for energy storage) .

I have a lincoln power mig 255 and every time i weld little holes appear in the welds. what could this be?


This could be a problem of gthe gas you are using. Make sure to use mix 75/25 argon/CO2 for mild steel welding, argon 100% for aluminum and trimix helium/argon/CO2 for stainless steel.
Also check your heat (voltage) 16-22 is enough for weld of most steels less than 1/2 inch.

Have a lincoln sp200. Trying to run aluminum wire not having any luck. I am running straight argon gas, I get basically a glow the wire melts no penetration. Do I need to reverse polarity or what. I...


You should only reverse polarity only if, before you were using innershield wire on the same MIG welder.
Your gun should be connected to + and ground to negative and you should use a spool gun for it.

Argon gas is ok, but for thick metals 1/4" and above you should use a mix of 75/25 argon/helium.

Good luck!

Oo is the lightest of the inert gases in periodic table and where is located?

Please go to the link below to see the periodic table. Incidently, it is Helium that is the lightest and that
why it is filled in baloons.

Some proplems face in welding aluminum

Are you asking about what the problems would be? First for mig welder, you can't push small aluminum wire through a very long cable. You need a teflon liner for it to work at all. A spool gun works better. Be sure to use correct gas for aluminum. Usually 100%argon, but some people use Argon/helium or helium. Use direct current reverse polarity (electrode positive) from constant voltage (CV) power supplies. If shallow penetration is required (i.e. for weld surfacing and cladding) straight polarity (electrode negative) can be used

How can you check to see if your microwave oven is working at full power

The following test will provide a suitably accurate measurement of the output power of any microwave oven. Variations or errors in performing this test will produce uncertain results. If the line voltage (from the electrical outlet) is low, the magnetron output will be correspondingly low.

Equipment needed:

- Microwave safe container with 1000 mL (1 Liter) gradation.
- Fahrenheit or centigrade thermometer


Pour exactly 1000 mL (1 Liter) of cool tap water into the container. Using the thermometer, stir the water, then measure and record the temperature. For accurate results the water should be about 60 degrees F (20 degrees C).

Place the container on the center of the oven cooking shelf (do not leave the thermometer in the container and remove any metal racks), and heat the water (at full power) for 63 seconds. Use the second hand of a watch, not the oven timer.

After the heating time is completed, immediately remove the container, stir the water, re-measure and record the temperature of the heated water.

Subtract the starting water temperature (step 2) from the ending water temperature (step 3) to obtain the temperature rise.

To determine the output power in watts, multiply the total temperature rise by a factor of 38.75 if you're using a Fahrenheit thermometer or 70 if you're using a centigrade thermometer.

We're happy to help and we appreciate your thoughtful rating of our answer.
