A sample of 240.0 K and 670 mm Hg occupies a 128 mL volume bottle. What volume will the gas occupy at -75 degrees celsius (If the pressure remains constant)?

New volume = 105.6 mL

Explanation:

Given that,

Temperature, T = 240.0 K

Pressure, P = 670 mm Hg

Volume, V = 128 mL

New temperature = -75°C = 198 K

We need to find the new volume. Let it is V'. The relation between volume and the temperature is given by :

So, the new volume is equal to 105.6 mL.

a: 45.9 meters

b: 4.29 seconds

step-by-step explanation:

a: h(t)=1/2(-9.8)(3)^2+0(3)+90

h(t)=-4.9(3)^2+90

h(t)=-44.1+90

h(t)=45.9 meters

b: 0=1/2(-9.8)(t^2)+0t+90

0=-4.9t^2+90

-90=-4.9t^2

18.37=t^2

t=4.29 seconds

in the second question, the numbers aren't exact, but they're a close approximation.
