28.8cm3 of nitrogen at 15°C is cooled to 0°C at constant pressure, the new volume of nitrogen is
- A) 17.4cm3
- B) 14.7cm3
- C) 27.3cm3
- D) 31.7cm3
Correct Answer: B) 14.7cm3
Explanation
To answer this question, we need to apply Charles's Law, which states that the volume of a gas is directly proportional to its temperature when the pressure is held constant. The formula for Charles's Law is:
\(V_1/T_1 = V_2/T_2\)
Where \(V_1\) and \(T_1\) are the initial volume and temperature of the gas, and \(V_2\) and \(T_2\) are the final volume and temperature of the gas.
First, we need to convert the temperatures from Celsius to Kelvin by adding 273 to each temperature:
\(T_1 = 15Post an Explanation Or Report an Error
