9.11 L

Explanation:

An arctic weather balloon is filled with 10.2 L of helium gas inside a prep shed. The temperature inside the shed is 9 °C. The balloon is then taken outside, where the temperature is -21 °C. Calculate the new volume of the balloon. You may assume the pressure on the balloon stays constant at exactly 1 atm. Round your answer to 3 significant digits.

Step 1: Given data

Step 2: Convert the temperatures to the Kelvin scale

We will use the following expression.

K = °C + 273.15

K = 9 °C + 273.15 = 282 K

K = -21 °C + 273.15 = 252 K

Step 3: Calculate the final volume of the balloon

We can calculate the final volume of the balloon using Charle's law.

V₁/T₁ = V₂/T₂

V₂ = V₁ × T₂/T₁

V₂ = 10.2 L × 252 K/282 K = 9.11 L

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.
