Atoms move faster when temperature is high. Example is in the gas phase. Atoms move slower in lower temperatures because molecules are contricted because they have no heat energy. Example is solid ice. Medium temperature example can be liquid water.

Describe the direction of the wind movement around the center of high air pressure
Artemon [7]

The coriolis force caused by the Earth's rotation is what gives winds within high-pressure systems their clockwise circulation in the northern hemisphere (as the wind moves outward and is deflected right from the center of high pressure) and counterclockwise circulation in the southern hemisphere (as the wind moves ...

In the operation of the Heat Transfer Service Unit, one of the variables you can control is the rate of cooling water flowing ag
max2010maxim [7]

Answer:

A. The rate of heat transfer through the material would increase.

Explanation:

To calculate the heat transfer in a heat exchanger you decide that there is not heat leakage to the surroundings, that means that  magnitude of the two transfer rates will be equal. Any heat lost by the hot fluid, is gained by the cold fluid. The equation that describes this is Q = m×Cp×dT

Where:

heat = mass flow ×specific heat capacity × temperature difference

So if we increase the rate of flow of cooling water and the other variables that ypu can control remain the same, the result is that the rate of heat transfer through the material would increase, as it is stated in option a.

What is the molarity of a 27.0% (v/v) aqueous ethanol solution? the density of ethanol (c2h6o, molar mass 46.07 g/mol) is 0.790
RoseWind [281]
   The  molarity  of a  27%(v/v) aqueous  ethanol  solution  is 4.63 M

         calculation
convert  27%(v/v) to  fraction  = 27ml/100 ml

use  density to  convert  27ml  to grams =  27 ml  x0.79 g/ml = 21.33 g

find  the number  of moles  of C2H6O

moles = mass/molar mass of C2H6O(46.07 g/mol)

moles is therefore = 21.33 g /46.07 g/mol =0.463  moles

find the  molarity =   moles /volume in liters

volume in liter =  100 ml/1000 = 0.1 L

molarity  is therefore =  0.463 mole/0.1 L = 4.63  M

Is the heart made up of at least 3 types of cells
Vilka [71]

Answer:

The human heart contains an estimated 2–3 billion cardiac muscle cells, but these account for less than a third of the total cell number in the heart.

Explanation:

the human heart Structure. There are two types of cells within the heart: the cardiomyocytes and the cardiac pacemaker cells. Cardiomyocytes make up the atria (the chambers in which blood enters the heart) and the ventricles (the chambers where blood is collected and pumped out of the heart).
