Answer:

Land and sea breeze

Explanation:

Specific heat differences between the land and ocean results in land and sea breeze occurring.

The ocean has a higher specific heat capacity. This implies that it requires more heat to cause an increase in temperature of a water body. In like manner, water loses heat very slowly.

The land has a low specific heat and it loses and gains heat faster.

During the day, air around the land area is warmer compared to that of the ocean.
The movement of air from the ocean to the land during the day is called the sea breeze.
The reverse process occurs in the night to form land breeze

Heavy rainfall causes a landslide. Hence, option A is correct.

<h3>What is a landslide?</h3>

A landslide is defined as the movement of a mass of rock, debris, or earth down a slope.

Water can trigger landslides and mudslides because it alters the pressure within the slope, which leads to slope instability.

Consequently, the heavy water-laden slope materials (soil, rock, etc.) will succumb to the forces of gravity.

Hence, option A is correct.

The pressure exerted by 1.5 mol of gas in a 13 L flask at 22 °C is ____ kPa

sukhopar [10]

Answer:

282.7KPa

Explanation:

Step 1:

Data obtained from the question.

Number of mole of (n) = 1.5 mole

Volume (V) = 13L

Temperature (T) = 22°C = 22 + 273°C = 295K

Pressure (P) =..?

Gas constant (R) = 0.082atm.L/Kmol

Step 2:

Determination of the pressure exerted by the gas.

This can be obtained by using the ideal gas equation as follow:

PV = nRT

P = nRT /V

P = 1.5 x 0.082 x 295 / 13

P = 2.79atm.

Step 3:

Conversion of 2.79atm to KPa.

This is illustrated below:

1 atm = 101.325KPa

Therefore, 2.79atm = 2.79 x 101.325 = 282.7KPa

Therefore, the pressure exerted by the gas in KPa is 282.7KPa

10 points !! Which can happen during a physical change?

Sveta_85 [38]

I think that the answer is A because if you think about water for an example. When water turns into ice, it's still technically water, just the molecules are frozen. The water is physically changed. It could also see why you think it is B but I don't think so completely. It doesn't really make sense to me. So I'd choose A. It's definitely not C or D.

A compound with a molar mass of 100.0 g/lol has an elemental composition of 24.0% C, 3.0% H, 16.0% O and 57.0%F. What is the mol

ch4aika [34]

If I made no mistake in calculation, the given answer must be correct...(tried my best)

elements   :                       carbon     hydrogen    oxygen       Fluorine

composition [C]                     24           3                16                57

M r                                          12             1                16                19

(divide C by Mr)                       2               3                 1                  3

(Divide by smallest value)       2                3                  1                  3

(smallest value = 1...so all value remained constant)

Empirical formula : C2H3OF3

if molar mas = 100 g per mole, then

first step calculate Mr. of empirical formula: [= 100]

Them molecular formula = empirical formula
