A 600ml sample of gas is heated from 27°C to 77°C at constant pressure. What is its finalvolume

To solve this problem, we can use Charles's Law, which states that the volume of a gas is directly proportional to its temperature, provided the pressure and the amount of gas remain constant. The formula for Charles's Law is V1/T1 = V2/T2, where:

• V1 is the initial volume
• T1 is the initial temperature
• V2 is the final volume
• T2 is the final temperature

Here's how to solve the problem step by step:

1. Convert all temperatures from Celsius to Kelvin. The formula to convert Celsius to Kelvin is K = °C + 273.15. So, T1 = 27°C + 273.15 = 300.15 K and T2 = 77°C + 273.15 = 350.15 K.

2. Plug the known values into Charles's Law formula. So, (600 ml / 300.15 K) = V2 / 350.15 K.

3. Solve for V2. Cross-multiply to get V2 = (600 ml / 300.15 K) * 350.15 K.

4. Calculate V2. V2 = 700 ml (rounded to the nearest whole number).

So, the final volume of the gas when it is heated from 27°C to 77°C at constant pressure is approximately 700 ml.
