Question

A student is asked, "A sample of nitrogen gas has a volume of 250 mL at 20.0C. What would the volume be if the temperature were increased to 40.0C?" The student got the WRONG answer of 500 mL. What step did they get wrong?

Answer 1

The student made a math error

Step-by-step explanation:

p/nR= T/V= constant (direct proportionality)

T(start) / V(start) = T(final) / V(final)

20 °C / 25 ml = 40 °C / V(final)

V(f) = 50 ml
