At a temperature of 15 degrees c, a quantity of oxygen has a volume of 250 ml. if it’s temperature is raised to 45 degrees c, what will it’s volume be?

280 mL

Explanation:

Ideal gas law:

PV = nRT

Rearranging:

V / T = nR / P

At constant pressure:

V₁ / T₁ = V₂ / T₂

Substituting values:

250 / (15 + 273) = V / (45 + 273)

V = 276

Rounded to two significant figures, the volume will be 280 mL.

When using the ideal gas law, remember to always use absolute units for temperature, like Kelvin.

for step 7 table c on the lab "newtons law of action"   the average time it took the car to travel .25 meters   was 1.92 seconds.

the average time it took the car to travel 0.50 meters was 2.61 seconds

hope this : )
