A475 cm3 sample of gas at 25c is heated to 45 c. what volume would the gas expand to in order to maintain the same pressure?

0.507 L or 507 cm³

Given,

Initial Volume, V1 = 475 cm³or 0.475 L

Initial temperature, T1 = 25 °C or 298.15 K (since, K = °C + 273.15)

Final temperature, T₂ = 45°C or 318.15 K

We can calculate the new volume;

Using the concept of Charles' law ;

Therefore,

To get, V2, we use;

Thus, the gas would expand to a volume of 0.507 L or 507 cm³ to maintain the same pressure.

so what is the problem with your lab report and whats the subject of the lab report? i will you
