Answer:

1.Fill in the blank with the correct term to make the statement true.

During the (night)

at the beach, the land cools down

(slower)

than the

(ocean).

Because of this, the air over the land is

(Warmer) than the air over the ocean. The

(More)

dense air rises over the ocean and the cooler,

(More)

dense air blows in from over the land creating a

(sea)

breeze.

2.Which statement is true about winds?

Winds always blow from low to high pressure.

true

Winds always blow from water to land.

false

Winds always blow from land to water.

false

3. Winds always blow from high to low pressure. How do landmasses impact the movement of air and water?

They stop all movement of both air and water.

They speed up the air and water and allow it to pass though.

They change the direction and slow them down.

think this is it

They slow down the air but speed up the water.

Espresso Coffee House is designing a coffee mug that keeps liquids hot. The research department tested several different materia
raketka [301]

Answer:

This question is incomplete

Explanation:

This question is incomplete because the result of the described experiment would have better determined the type of scientific explanation to profer. However, the type of material that will preserve the relative hotness or temperature of the hot coffee for the longest time will be a material than can resist heat transfer. These materials tend to keep hot substances hot by not allowing the heat of the coffee to be conducted or pass through it. These materials are mostly insulators or made by placing an insulator between two heat conductors.

Generally, heat is usually transferred from a region of higher concentration to a region of lower concentration, hence when the heat is denied of this transfer, the heat will remain trapped in the "heat-donor" substance (in this case the hot coffee). Thus, the material chosen (A, B or C) will be the material that resists heat transfer the most based on the explanation above.

How many liters of oxygen are required to react completely with 14.8 mol of Al?
Bond [772]

Answer:

296 L  

Explanation:

We will need a balanced equation with moles, so let's gather all the information in one place.

                  4Al + 3O₂ ⟶ 2Al₂O₃

n/mol:        17.4

1. Moles of O₂

n = \text{17.4 mol Al}\times \dfrac{\text{3 mol O}_{2}}{\text{4 mol Al}}= \text{13.05 mol O}_{2}

2. Volume of O₂

You haven't given the conditions at which the volume is measured, so I assume it is at STP (0 °C and 1 bar).

At STP the molar volume of a gas is 22.71 L.

V = \text{13.05 mol}\times \dfrac{\text{22.71 L}}{\text{1 mol }}= \textbf{296 L}
