Question

Based on the trend in the table, hypothesize what the volume of the sample at 400K would be.

a. 247 cm^3
b. 285 cm^3
c. 297 cm^3
d. 400 cm^3

Answer 1

D

Explanation: 400 cm

Answer 2

Answer: The volume of sample at 400 K is
`285cm^3`

Step-by-step explanation:

Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.

`V\propto T` (At constant pressure and number of moles)

`{(V_1)/(T_1)=(V_2)/(T_2)`

where,

`V_1` = initial volume of gas =
`257cm^3`

`V_2` = final volume of gas = ?

`T_1` = initial temperature of gas = 360 K

`T_2` = final temperature of gas = 400 K

Putting in the values we get:

`{(257)/(360)=(V_2)/(400)`

`V_2=285cm^3`

Thus volume of sample at 400 K is
`285cm^3`
