Question

A man heats a ballon in the oven. The balloon initially has a volume of 0.4 L and a temperature of 20°C what will the volume of the balloon be after he heats it to 250°

Answer 1

Answer: The volume of the balloon be after he heats it to 250°C is 0.7 L

Step-by-step explanation:

To calculate the final volume 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=0.4L\\T_1=20^oC=(20+273)K=293K\\V_2=?\\T_2=250^oC=(250+273)K=523K`

Putting values in above equation, we get:

`(0.4)/(293)=(V_2)/(523)\\\\V_2=0.7L`

Thus the volume of the balloon be after he heats it to 250°C is 0.7 L
