Question

A gas has a volume of 4.70 L at 0 ∘C. 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) 1.60 L

b) 1800 mL

c) 51.0 mL

Answer 1

As we know from Charles' Law that at constant Pressure '' the volume of a gas is directly proportional to the absolute temperature''

So we can write that

For all case Temperature is

A) Here

Now apply

The final temperature is 92.93 K.

B)

Here

Now apply

The final temperature is 104.55 K

C)

Here

Now apply

The final temperature is 2.96 K.
