A sample of ideal gas is in a sealed container. The pressure of the gas is 485 torr , and the temperature is 40 ∘C . If the temp
Fantom [35]

Answer:

537.68 torr.

Explanation:

  • We can use the general law of ideal gas:<em> PV = nRT.</em>

where, P is the pressure of the gas in atm.

V is the volume of the gas in L.

n is the no. of moles of the gas in mol.

R is the general gas constant,

T is the temperature of the gas in K.

  • If n and V are constant, and have different values of P and T:

<em>(P₁T₂) = (P₂T₁).</em>

P₁ = 485 torr, T₁ = 40°C + 273 = 313 K,

P₂ = ??? torr, ​T₂ = 74°C + 273 = 347 K.

∴ P₂ = (P₁T₂)/(P₁) = (485 torr)(347 K)/(313 K) = 537.68 torr.

Which factor most likely facilitates mass movement after heavy rains in a dry region?
melomori [17]

Answer: Option (b) is the correct answer.

Explanation:

The process in which sediment moves downhill is known as mass movement.

Different types of mass movement are landslides, mud slides, slump, creep etc.

Mud flow contains mass of saturated rock particles of all sizes. Mud flow arises due to sudden flood of water or due to heavy rain in a dry region (semi-arid region). Soil and rocks from a large slope area flow along with the flood water and gets washed to a gulch or canyon.

As a result, debris and water moves down canyon and lay out on the gentle slopes below.

Thus, we can conclude that mud flow is most likely facilitates mass movement after heavy rains in a dry region.

Todd drives west to work;54km on way in 1.5hours and then drives home in 2hrs. What is his velocity on the way to work? What is
Nataly [62]

Answer:

Explanation:

Velocity ​​is a physical quantity that expresses the relationship between the space traveled by an object, the time taken for it and its direction. In other words, velocity is associated with the change of position of a body over time.

Its unit in the International System of Units is the meter per second (\frac{m}{s}), but it can also be expressed in \frac{km}{hr}

So, in this case, the speed on the way to work will be:

velocity=\frac{54 km}{1.5 hours}

velocity= 36 \frac{km}{hr}

The velocity on the way back home will be:

velocity=\frac{54 km}{2 hours}

velocity= 27 \frac{km}{hr}
