A certain amount of gas is trapped in a nonrigid container at atmospheric pressure. If the container is cooled and the gas in th

Akimi4 [234]

Answer:

D. The volume of the container will decrease.

Explanation:

We apply here, the general gas law of ideal gases:

PV = nRT,

where, P is the pressure of the gas.

V is the volume of the container.

n is the no. of moles of the gas.

R is the general gas constant.

T is the temperature of the gas.

We are given that P is constant.

Also, n is constant as there is no added external gases.

T is decreased as the container is cooled.

So, the volume will change as the container is nonrigid.

V α T.

The volume is directly proportional to the temperature,

Thus, as the container is cooled, the T will decrease, and the volume of the container will decrease.

Caculate the mass of a solid with a density of 14.2 g/cm cubed and a volume of 350 cm cubed

shepuryov [24]

Answer:

The mass of solid with density 14.2 g/cm3 and volume 350 cm3 is 4.97 Kg.

Explanation:

Formula for density is given below :

$density = \frac{mass}{volume}$

$volume = 350 cm^{3}$

$density = 14.2 g/cm^{3}$

Insert the values in the formula

$14.2 = \frac{mass}{350}$

on cross multiplication :

$mass = density\times volume$

$mass = 14.2\times 350$

$mass = 4970 g$

1 g = 0.001 Kg

$mass =4970\times 0.001 Kg$

mass = 4.97 Kg

Note : Check the units of volume and density carefully

Compare the rates of effusion for carbon monoxide and carbon dioxide gases

Airida [17]

According to Grahams law the rate of effusion of a gas is inversely proportional to the square root of it's molecular weight. The rate of diffusion is the measure of rate at which two gases mix. From this law we can say that for the two gases carbon monoxide and carbon dioxide, the rate of effusion of carbon monoxide is greater than that of carbon dioxide, this is because carbon monoxide is lighter (28 g) compared to carbon dioxide (44 g).
