Charles law states that volume of gas is directly proportional to volume of gas at constant pressure
parameters for the first instance are on the left side and parameters for the second instance are on the right side of the equation
where
V - volume
T - temperature in kelvin
T1 - 123 °C + 273 = 396 K
T2 - 468 °C + 273 = 741 K
substituting the values
V = 38.29 L
new volume is 38.29 L
C. The maximum energy required to move one electron to the valence shell.
Answer: Option A) 25mL
Explanation:
Given that,
Original volume of gas (V1) = 75mL
Original temperature of gas (T1) = 450K
New volume V2 = ?
New temperature T2 = 150K
Since volume and temperature are given while pressure is held constant, apply the formula for Charle's law
V1/T1 = V2/T2
75mL/450K = V2/150K
To get the value of T2, cross multiply
75mL x 150K = 450K x V2
11250mL•K = 450K•V2
Divide both sides by 450K
11250mL•K / 450K = 450K•V2/450K
25mL = V2
Thus, the new volume of the gas is 25mL
<span>The round trip is 12.5 miles * 2 way = 25 miles. In order to accomplish this in 45 minutes, or 45/60 = 0.75 hours, Tyrone would have to drive at a speed of 25 miles / 0.75 hours = 33.3 miles per hour. If he were to actually be able to drive continuously at this speed without stopping and the prescription pickup were instantaneous, then he would be able to make the round trip in time. However, in the real world this is unlikely to be the case.</span>
