Asample of helium has a volume of 12.7 m3. the temperature is raised to 323 k at which time the gas occupies 32.5 m3? assume pressure is constant at 3 atm. what was the original temperature of the gas?

The original temperature was

Explanation:

Let's put the information in mathematical form:

If we consider the helium as an ideal gas, we can use the Ideal Gas Law:

were R is the gas constant. And n is the number of moles (which we don't know yet)

From this, taking ,  we have:

⇒

Now:

⇒

126.22

an ion is a charged atom or molecule. it is charged because the number of electrons do not equal the number of protons in the atom or molecule. an atom can acquire a positive charge or a negative charge depending on whether the number of electrons in an atom is greater or less then the number of protons in the atom.

0.3x0.21x0.08kg=mass 1 sheet

mass 500 = 500xmass 1

volume pile = 0.3x0.2x0.048

density=mass/volume= 500xmass 1/0.3x0.2x0.048
