ITS URGENT PLZ HELP

calculate the volume of a gas when the temperature is decreased to 280 K if the initial volume at 350 K was 2.5 L.

Answer 1

Answer:

2 L

Step-by-step explanation:

At constant pressure, the volume of a gas is proportional to its temperature.

Therefore, we can write $\frac{V_{2} }{V_{1} } =\frac{T_{2} }{T_{1} }$ ....... (1) at pressure = constant.

Given that the initial volume ($V_{1}$) = 2.5 L and initial temperature ($T_{1}$) = 350 K

And the final temperature ($T_{2}$) = 280 K

Therefore, from equation (1) we get final volume ($V_{2}$) = $\frac{280 \times 2.5}{350} =2$ L (Answer)
