In 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.
<h3>What is James Webb Telescope?</h3>
The James Webb Telescope is the most important optical telescope present in space, which is employed by astronomers to observe celestial bodies and physical phenomena in the universe.
This space telescope (James Webb Telescope) is based on the infrared wavelengths that cover a specific length of 0.57 to 28-micrometer waves and enable to observe different spectra across the Universe.
In conclusion, in 2021 the James Webb Telescope will begin operation focusing on infrared wavelengths and must be kept extremely cold.

Answer:
V₂ = 285 mL
Explanation:
Given data:
Initial volume of bag = 250 mL
Initial temperature = 19.0°C
Final temperature = 60.0°C
Final volume = ?
Solution:
The given problem will be solved by using Charles Law,
This law stated that " The volume of given amount of gas at constant pressure and constant number of moles is directly proportional to its temperature"
Mathematical relationship:
V₁/T₁ = V₂/T₂
Now we will convert the temperature into kelvin.
Initial temperature = 19.0 + 273 = 292K
Final temperature = 60.0 + 273 = 333K
Now we will put the values in formula:
V₁/T₁ = V₂/T₂
250 mL / 292K = V₂/ 333K
0.856 mL /K = V₂/ 333K
V₂ = 0.86×333K. mL /K
V₂ = 285 mL
