A rigid container is charged with a gas to a pressure of 740 mmHg at 40.0°C and tightly sealed.If the temperature of the gas increases by 80.0°C what is the new pressure?
A)1480 mmHg
B)589 mmHg
C)551 mmHg
D)929 mmHg
E)1110 mmHg

Using the formula for Charles's Law (V1/T1 = V2/T2) and assuming the volume remains constant (since the container is rigid), we can solve for the new pressure. Rearranging the formula, we get P2 = (P1*T2)/T1 = (740* (40+80)) / (40) = 1480 mmHg. Therefore, the new pressure is 1480 mmHg, which is choice D.
