Question

2. From the data table given , calculate the missing quantity.

Answer 1

Answer: The final temperature of the gas is 25 K

Step-by-step explanation:

To calculate the final temperature of the system, we use the equation given by Charles' Law. This law states that volume of the gas is directly proportional to the temperature of the gas at constant pressure.

Mathematically,

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

where,

`V_1\text{ and }T_1` are the initial volume and temperature of the gas.

`V_2\text{ and }T_2` are the final volume and temperature of the gas.

We are given:

`V_1=22.4L\\T_1=200K\\V_2=2.8L\\T_2=?K`

Putting values in above equation, we get:

`(22.4L)/(200K)=(2.8L)/(T_2)\\\\T_2=(2.8* 200)/(22.4)=25K`

Hence, the final temperature of the gas is 25 K
