A tube is filled with hydrogen gas to a volume of 10dm3 at a temperature of 30 degree Celsius. If this tube is heated to a temperature of 100 degree Celsius, what will be the new volume of the tube?

Esther go and read your notes

Step-by-step explanation:

V1: 10dm^3

V2:?

T1: 30+273=303K

T2: 100+273=373K

Using Charles law…

V1/T1=V2/T2

Substituting values…

10/303=V2/373

Cross multiply…

373*10=303V2

3730=303V2

3730/303=303/303 V2

21.31=V2

Therefore; V2= 21.31dm^3

Good luck in the quiz!

Final answer:

According to Charles's Law, the volume of a gas is directly proportional to its temperature in Kelvin, assuming pressure and amount of gas are held constant. Using the formula V1/T1 = V2/T2, we can find the new volume of the tube. Plugging in the values, we get V2 = (10 * 373) / 303 = 12.43 dm³.

Step-by-step explanation:

When a gas is heated, its volume generally increases. This relationship between temperature and volume is described by Charles's Law. According to Charles's Law, the volume of a gas is directly proportional to its temperature in Kelvin, assuming pressure and amount of gas are held constant.

To solve this problem, we need to convert the initial and final temperatures to Kelvin. The initial temperature is 30 degrees Celsius, which is 303 Kelvin. The final temperature is 100 degrees Celsius, which is 373 Kelvin. Now we can use the formula V1/T1 = V2/T2 to find the new volume.

Plugging in the values, we have 10/T1 = V2/373. Solving for V2, we get V2 = (10 * 373) / 303 = 12.43 dm³. Therefore, the new volume of the tube is 12.43 dm³.
