Temperature cloud cover and thunder are all examples of
Umnica [9.8K]

Temperature, cloud cover and thunder are all examples of weather.  

<h3><u>Explanation:</u></h3>

Weather is described as conditions that prevail for a short period of time and the above-mentioned factors change variably throughout the day. Cloud cover simply describes the clouds coverage in the sky. It is one factor that is used to describe weather conditions since the type of clouds indicates prevailing weather.

For example, the presence of cirrus means there will be a storm in 24 to 48 hours. Weather conditions characterized by thunder is said to be stormy and it also has other conditions such as lightning, wind and fast rain with heavy raindrops. Temperature affects the warmness and coldness of the air and its movement. Moreover, it also affects all other aspects of weather conditions.

V2 = (P1 × V1 × T2) (P2 × T1) A gas with a beginning pressure of 2 atm at a temperature of 300 K has a volume of 20 ml. What wil
rusak2 [61]

6.6ml will be the new volume if the pressure increases to 4 atm and the temperature are lowered to 200 K.

<h3>What is an ideal gas equation?</h3>

The ideal gas law (PV = nRT) relates the macroscopic properties of ideal gases. An ideal gas is a gas in which the particles (a) do not attract or repel one another and (b) take up no space (have no volume).

Given data:

V_1=20 ml

T_1=3

P_1=2 atm

T_2=200 K

P_2=4 atm

V_2=?

Using equation:

V_2 = \frac{P_1 X V_1 XT_2}{P_2 X T_1}

V_2 =\frac{2 atm  X 20 ml X200 K}{4 atm  X 300 K}

V_2 = 6.6 ml

Hence, 6.6ml will be the new volume if the pressure increases to 4 atm and the temperature are lowered to 200 K.

Which of the following measurements is equal to 150 dL?
MrRissso [65]
This is a case of metric system of measurements. The scale of the metric system only differs by a factor of 10. The scale (from greatest to least) is kiloliter, hectoliter, dekaliter, liter, deciliter, centiliter and milliliter. If the unit is 150 dL, and you want to find the equivalent dkL measurement, just move the decimal point 2 decimals places to the left (just follow the scale). The same procedure is done for the other metric units.

150 dL = 1.5 dkL
150 dL = 15 L
150 dL = 1,500 cL
150 dL = 15,000 mL

From the choices, the answer is letter C.

How many molecules are in 9.8 grams of calcium
solniwko [45]
Molar mass of Calcium ( Ca ) = 40.078 g/mol

Number of moles in 9.8 grams :

1 mole Ca -----------> 40.078 g
mole Ca -------------> 9.8 g

moles Ca = 9.8 / 40.078

moles Ca = 0.2445 moles

number of molecules:

1 mole ----------------> 6.02x10²³ molecules
0.2445 moles --------> ?

= 0.2445 * 6.02x10²³

= 1.47x10²³ molecules

hope this helps!.
