DA gas has a volume of 4.00 L at 0 degrees Celsius. What final temperature, in degrees Celsius, is needed to change the volume of the gas to each of the following, if n and p do not change?
A. 1.50 L
B. 1200 mL
C. 10.0 L
D. 50.0 mL

Respuesta :

D 50.O ML IS THE ANSWER

The final temperature is  -170.625 degree Celsius ,-191.1 degree C, 409.5 degree C,-272.66 degrees Celsius .

What is Charle's Law ?

According to Charle's Law , For an Ideal Gas , the volume is directly proportional to temperature when no. of moles and Pressure remains constant.

It is given in the question that

A gas has a volume of 4.00 L

T = 0 degree Celsius = 273 K

T' = ? for each scenario

the volume of the gas = 1.5 l , 1200ml , 10 l , 50ml

if n and p do not change

[tex]\rm \dfrac{V_1}{T_1} = \dfrac{V_2}{T_2}[/tex]

For V₂ = 1.5 l

4 / 273 = 1.5 / T₂

T₂ = 1.5*273/4

T₂ = 102.375 K = -170.625 degree Celsius

For  V₂ = 1.2 l

4/273 = 1.2/T₂

T₂ = 81.9 K = -191.1 degree C

For  V₂ = 10 l

4/273 = 10/T₂

T₂ = 682.5 K= 409.5 degree C

For  V₂ = 50/1000= 0.005L

4/273 = 0.005/T₂

T₂ = 0.34125 K= -272.66 degree C

Therefore the final temperature in degrees Celsius has been determined.
