There are two important isotopes of uranium— and ; these isotopes are nearly identical chemically but have different atomic mass
lana [24]

Answer:

 

Explanation:

The relation between average velocity of a gas molecules and its molecular mass is as follows .

average velocity v

v = k \sqrt{\frac{1}{M} } where k is a constant .

If v₁ and v₂ be the velocities corresponding to molecular masses 349 and 352 .

\frac{v_1}{v_2 } = \sqrt{\frac{M_2}{M_1} }

\frac{v_1}{v_2 } = \sqrt{\frac{352}{349} }

= 1.004

A balloon is filled with 30.0 L of helium in the morning when the temperature is 25.00 ℃. By noon the temperature has risen to 5
Korolek [52]

Answer:

33.0 L

Explanation:

Step 1: Given data

  • Initial volume of the balloon (V₁): 30.0 L
  • Initial temperature (T₁): 25.00 °C
  • Final volume of the balloon (V₂): ?
  • Final temperature (T₂): 55.00 °C

Step 2: Convert the temperatures to the Kelvin scale

We will use the following expression.

K = °C + 273.15

T₁: K = 25.00°C + 273.15 = 298.15 K

T₂: K = 55.00°C + 273.15 = 328.15 K

Step 3: Calculate the final volume of the balloon

If we assume ideal behavior, we can calculate the final volume of the balloon using Charles' law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 30.0 L × 328.15 K/298.15 K = 33.0 L
