What is the relationship between the number of gas particles and volume ?
choli [55]

Answer:

V ∝ n  

Step-by-step explanation:

Suppose that pressure and temperature are constant.

If you try to force more molecules of air into a balloon, the balloon will expand.

This is an example of <em>Avogadro's Law</em>: the volume of a gas is directly proportional to the number of moles (particles).

Convert 32.56 km/hr into ft/hr
Gekata [30.6K]
Note that
1 m = 3.2808 ft

Therefore
1 km = 3280.8 ft
and
32.56 \,  \frac{km}{h} = (32.56 \,  \frac{km}{h})*(3280.8 \,  \frac{ft}{km}) =  1.0682 \, \times 10^{5} \, \frac{ft}{h}

Answer: 1.0682 x 10⁵ ft/hr
