Question

If the temperature of 9.3 L of a gas at 6.5 ºC falls by 6.1 Cº, what is the new volume of the gas if the pressure is constant?

Select one:
a. 9.10
b. 9.29
c. 0.0133
d. 45.74

Answer 1

I believe 9.29 for temperature

Answer 2

b. 9.29 L is the new volume of the gas if the pressure is constant.

Step-by-step explanation:

As per Charles’s law

At constant pressure for a given amount of a gas,

Volume is directly proportional to its temperature.

Thus the expression is
`V \propto T`

`\frac {V}{T} = k` where k is a constant

When there is a change in the volume and temperature the expression will be

`\frac {V_1}{T_1} = \frac {V_2}{T_2}`

where
`V_1` and
`T_1` are the initial volume and initial temperature and
`V_2` and
`T_2` are the final volume and temperature.

Plugging in the values given

`\frac {(9.3L)}{(279.5K)}=\frac {V_2}{(279.1K)}`

`V_2=\frac {(9.3L*279.1K)}{279.5K} \\\\=9.29L`
