Question

A gas in a balloon at constant pressure has a volume of 185 mL at -125*C. What is its volume at 31.0*C? Show all work including what equation or gas law you use.

Answer 1

Answer:

380 mL is the new volume

Explanation:

At constant pressure.

V₁ / T₁ = V₂ / T₂

Temperature must be in Absolute Values (T°K = T°C + 273)

-125°C + 273 = 148 K

31°C + 273 = 304 K

185 mL / 148 K = V₂ / 304 K

V₂ = (185 mL / 148 K) . 304 K → 380 mL
