Question

A sample of nitrogen gas has a pressure of 5.68 kPa at 532K. If the volume does not change, what will the pressure be at -61°C.

Answer 1

Answer: 2.26 kPa

Step-by-step explanation:

Since the volume is constant, the equation: P/T = P/T can be used.

However, before plugging in numbers, the second temperature must be converted in kelvin: -61 + 273 =212K.

Now, use the original formula: 5.68 / 532 = P / 212 → Cross multiply and then divide to get the answer, P = 2.26 kPa :)
