Answer: 8.23L
Explanation:
Initial volume of nitrogen V1 = 7.2 L
Initial temperature T1 = 25 °C
Convert temperature in Celsius to Kelvin
(25 °C + 273 = 298K)
New volume V2 = ?
New Temperature T2 = 70 °C
(70°C + 273 = 343K)
Since, volume and temperature are involved while pressure is constant, apply the formula for Charles' Law:
(V1/T1) = (V2/T2)
7.2L/298K = V2/343K
0.024 = V2/343K
To get V2, cross multiply
V2 = 0.024 x 343
V2 = 8.23L
Thus, the new volume of nitrogen is 8.23 liters
