Using the Combined Gas Law Part B rature relationships for a single relationship law. This expression the effect of changes he third as long as the oles) remains constant properly, you must ures in kelvins. The presented as followS Consider 4.60 L of a gas at 365 mmHg and 20. C. If the container is compressed to 2.70 L and the temperature is increased to 32 °C, what is the new pressure, P2, inside the container? Assume no change in the amount of gas inside the cylinder. Express your answer with the appropriate units. View Available Hint(s) 72 626 mmHg Submit Previous Answers X Incorrect; Try Again; 8 attempts remaining Not quite. Check through your calculations; you may have made a rounding error or used the wrong number of significant figures.

Explanation / Answer

Using the combined gas it can be derived from the ideal gas equation, or from the laws of Boyle and Charles. The combined gas law assumes a fixed number of moles of gas.

P1V1 / T1 = P2V2 / T2
P2 = P1V1T2 / (T1V2)
P2 = 365 mmHg x 4.60L x 305K / 293K *2.70L
P2 = 647.3202 mmHg
