Answer:
286.3 mL
Explanation:
The question specifies that pressure was held constant, this immediately reminds us of Charles law. The volume of a given mass of has is directly proportional to its temperature at constant pressure.
From
V1/T1 = V2/T2
V1= initial volume = 360 ml
T1 = initial temperature= 20°C +273= 293K
T2= final temperature= -40°C + 273= 233K
V2= final volume = ?????
V2= V1T2/T1
V2= 360 × 233/ 293
V2= 286.3 mL
Answer:
The answer is: B. 286 mL
Explanation:
Given:
V₁ = 360 mL = 0.36 L
T₁ = 20°C = 293 K
T₂ = -40°C = 233 K
Constant pressure
Question: What is the new volume of the gas, V₂ = ?
The relation between the temperature and the volume at constant pressure is known like the Charles's law
[tex]V_{2} =\frac{V_{1}T_{2} }{T_{1} } =\frac{0.36*233}{293} =0.2863L=286.3mL[/tex]
