1. What is the cause of the Coriolis effect?

2 answers:

1.) The answer would be D.Earth's rotation, since the rotation makes the air and wind direction appear to be going in a different direction than it really is due to the earth rotating (this deflects the winds)
2.) The answer would be C.Relative Humidity, since this is ratio of water vapor in the air to a given area, while humidity is simply the amount of water vapor in the air in general.
3.) B. Warm Front, since cold fronts usually bring stormy weather, while the weather conditions brought by a warm front are typically more mild.
4.) For this one, I'm not sure, but I'm pretty sure the closest answer would be C.4. The way I have learned this is that there have been 5 major ice ages, however the choice isn't on there.

A canister has a fixed volume. If the pressure of the cannister is 1.5 atm at 25 Celsius, what is the new pressure if the temper

scoray [572]

Answer:

d) 1.8 atm

Explanation:

According to Boyle's Law,

P₁/T₁ = P₂/T₂

Here, we are given :

P₁ = 1.5 atm
T₁ = 25°C = 298 K
T₂ = 75°C = 348 K

Solving

P₂ = P₁T₂/T₁
P₂ = 1.5 x 348 / 298
P₂ = 522/298
P₂ = 1.8 atm (approximately)

What information can a mineralogist learn from testing the mass and volume of a mineral?

Vesna [10]

Minerals can be identified by their physical characteristics. The physical properties of minerals are related to their chemical composition and bonding. Some characteristics, such as a mineral’s hardness, are more useful for mineral identification. Color is readily observable and certainly obvious, but it is usually less reliable than other physical properties.

During the discussion of gaseous diffusion for enriching uranium, it was claimed that 235UF6 diffuses 0.4% faster than 238UF6. S

Kay [80]

Answer: The below calculations proves that the rate of diffusion of $^{235}UF_6$ is 0.4 % faster than the rate of diffusion of $^{238}UF_6$

Explanation:

To calculate the rate of diffusion of gas, we use Graham's Law.

This law states that the rate of effusion or diffusion of gas is inversely proportional to the square root of the molar mass of the gas. The equation given by this law follows the equation:

$\text{Rate of diffusion}\propto \frac{1}{\sqrt{\text{Molar mass of the gas}}}$

We are given:

Molar mass of $^{235}UF_6=349.034348g/mol$

Molar mass of $^{238}UF_6=352.041206g/mol$

By taking their ratio, we get:

$\frac{Rate_{(^{235}UF_6)}}{Rate_{(^{238}UF_6)}}=\sqrt{\frac{M_{(^{238}UF_6)}}{M_{(^{235}UF_6)}}}$

$\frac{Rate_{(^{235}UF_6)}}{Rate_{(^{238}UF_6)}}=\sqrt{\frac{352.041206}{349.034348}}\\\\\frac{Rate_{(^{235}UF_6)}}{Rate_{(^{238}UF_6)}}=\frac{1.00429816}{1}$

From the above relation, it is clear that rate of effusion of $^{235}UF_6$ is faster than $^{238}UF_6$

Difference in the rate of both the gases, $Rate_{(^{235}UF_6)}-Rate_{(^{238}UF_6)}=1.00429816-1=0.00429816$

To calculate the percentage increase in the rate, we use the equation:

$\%\text{ increase}=\frac{\Delta R}{Rate_{(^{235}UF_6)}}\times 100$

Putting values in above equation, we get:

$\%\text{ increase}=\frac{0.00429816}{1.00429816}\times 100\\\\\%\text{ increase}=0.4\%$

The above calculations proves that the rate of diffusion of $^{235}UF_6$ is 0.4 % faster than the rate of diffusion of $^{238}UF_6$
