Answer:

A.   it is the lowest at low temperatures

Explanation:

It is true with respect to the kinetic energy of a molecule that the it is the lowest at low temperatures.

The kinetic energy of a molecule is the energy due to the motion of the particles within a substance.

  • Kinetic energy is directly proportional to the temperature of a substance.
  • The higher the temperature, the more the kinetic energy of the molecules within a system.
  • At low temperature, kinetic energy is the lowest.
  • At the highest temperature, kinetic energy is the highest

From each drop-down menu, a solid has (a definite volume and a definite shape), a Liquid has (a definite volume) and gas has ( non of the above)

<h3>The features of different states of Matter:</h3>

Matter is defined as anything that has weight and occupies space.

There are three states of matter that is in existence which include:

  • Solid: The particles of solid are closely packed together and vibrate around fixed axes. That is why they have a definite shape and volume.

  • Liquid: The particles of liquid, though attracted to each other,move freely over each other. That is why they have definite volume but not a definite shape.

Therefore, a liquid occupies the shape of its container.

  • Gas: The particles of gas contain scattered molecules that are dispersed across a given volume.

Therefore, a gas neither has a definite shape nor volume.

A factor whose value is graphed on the y-axis is called
Pie

Answer: dependent variable

Explanation:In single variable calculus, a function is typically graphed with the horizontal axis representing the independent variable and the vertical axis representing the dependent variable. In this function, y is the dependent variable and x is the independent variable.

The tallest mast in the world is the KTHI-TVmast in Branchard, which measures 2063 feet , what is the expressed in meter?
Amanda [17]
1ft=.3048meter

So if we have 2063ft and want it in meters we just do a simple unit conversion.

(2063ft)(.3048meters/1ft)=628.8meters. Here ft cancel out and leave us with meter units.

Any questions please feel free to ask. Thank you.

The pressure system begins at 99.7 kpa.the volume of the gas is 150ml . What would be the final volume in the system if the pres
____ [38]
Assuming ideal behavior of the gas for a fixed amount when temperature is held constant, the pressure and volume are inversely proportional as given by the expression
     P1V1 = P2V2 
where the terms with subscripts of one represent the initial conditions for pressure and volume of the gas while for terms with subscripts of two represent the final  conditions. 
Rearranging the Boyle's law equation to calculate for the final volume V2:
     V2 = P1V1 / P2
     V2 = (99.7 kPa)(150 mL) / 99.8 kPa
     V2 = 149.85 mL

How many grams of sulfur trioxide are produced 18 mol O2 react with sufficient sulfur? Show all your work S8 +12O 2&gt; 8SO3
SOVA2 [1]

Answer:

m_{SO_3}=2.31x10^4gSO_3

Explanation:

Hello!

In this case, since the reaction between sulfur and oxygen is:

S_8 +\frac{1}{2} O_2 \rightarrow 8SO_3

Whereas there is a 1/2:8 mole ratio between oxygen and SO3, and we can compute the produced grams of product as shown below:

m_{SO_3}=18molO_2*\frac{8molSO_3}{1/2molO_2} *\frac{80.06gSO_3}{1molSO_3} \\\\m_{SO_3}=23,057.3gSO_3=2.31x10^4gSO_3

Best regards!
