`i am holding a balloon containing 439 ml of gas over my fireplace. the temperature and pressure of the gas inside the balloon is 317.15 k and 0.959 atm, respectively. suppose i don't want the pressure to change, but i want to the volume to go down to 0.378 l. what is the temperature that i need to reach when i cool down the balloon? to what temperature (in celsius) must the balloon be cooled to reduce its volume to 0.378 l if the pressure doesn't change (remained constant)?

- 0.07 °C

Explanation:

At constant pressure and number of moles, Using Charle's law  

Given ,  

V₁ = 439 mL  = 0.439 L ( 1 L = 0.001 mL )

V₂ = 0.378 L

T₁ = 317.15 K

T₂ = ?

Using above equation as:

The conversion of T(K) to T( °C) is shown below:

T( °C) = T(K) - 273.15  

So, T = 273.08 - 273.15 °C = - 0.07 °C

the correct name for the n3 ion is azide. azide is a polyatomic anion with a -1 charge and is written as n3 -1. it consists of three nitrogen atoms bonded together. hope i . let me know if you need anything else.
