Answer: The correct answer is Atom.

Explanation:

Atom consists of proton, electron, neutron and nucleus. The subatomic particles of the atom are electron, proton and neutron.

The electrons revolve around the nucleus while neutrons and protons are located in nucleus. The whole mass of the atom is supposed to be concentrated at nucleus.

The electron is negatively charged particle. The proton is positively charged particle. The neutron has no charge. It is neutral.

Therefore, the correct option is B.

A very flexible helium-filled balloon is released from the ground into the air at 20. ∘C. The initial volume of the balloon is 5

koban [17]

Answer:

V = 38.0 L

Explanation:

As we know that number of moles will remains conserved inside the balloon

so we will have

$moles = \frac{PV}{RT}$

here we have

$\frac{P_1V_1}{RT_1} = \frac{P_2V_2}{RT_2}$

now we have

$P_1 = 760 mm Hg$

$P_2 = 76 mm Hg$

$V_1 = 5.00 L$

$T_1 = 20^o C = 293 K$

$T_2 = -50^o C = 223 K$

$\frac{(760mm Hg)(5L)}{R(293)} = \frac{(76mm Hg)(V)}{R(223)}$

$V = 38.0 L$
