A group of students wants to investigate the effects of plant moisture on the growth of caterpillars. The students fill three id

entical boxes with an equal number of a kind of leaf that caterpillars eat. The students keep the leaves in the first box dry, spray the leaves in the second box with two sprays of water, and spray the leaves in the third box with four sprays of water. The students then add four caterpillars to each box. Every day, the length of the caterpillar is measured, recorded and the results are averaged. What is the tested (independent) variable in this experiment?

Water H20, is made up of different elements, hydrogen and oxygen. Is this type of combination a mixture or pure substance?
vlabodo [156]
Believe it or not it’s a pure substance, two hydrogen atoms combine with one oxygen atom chemically, forming a new substance that has properties different from hydrogen alone or oxygen alone.

Convert 1.25 atm to bar.
Tasya [4]

Answer: 1.27 bar

Explanation:

1 atm = 1.01325 bar

1.25 atm = Z (let Z be the unknown value)

To get the value of Z, cross multiply

Z x 1 atm = 1.25 atm x 1.01325 bar

1 atm•Z = 1.2665625 atm•bar

To get the value of Z, divide both sides by 1 atm

1 atm•Z/1 atm = 1.2665625 atm•bar/1atm

Z = 1.2665625 bar

(Round up Z to the nearest hundredth as 1.27 bar)

Thus, 1.25 atm when coverted gives 1.27 bar

the compressor exerts a pressure of 400 Pa to compress nitrogen gas from 3 L to 1 L. If no heat transfer occurs, how much will t
Triss [41]

Answer:

0.79014 J

Explanation:

According to the first law of thermodynamics:-

\Delta U = q + w

Where,  

U is the internal energy

q is the heat

w is the work done

From the question,

q = 0 J

The expression for the calculation of work done is shown below as:

w=P\times \Delta V

Where, P is the pressure

\Delta V is the change in volume

From the question,  

\Delta V = 3 - 1 L = 2 L

P = 400 Pa

The expression for the conversion of pressure in Pascal to pressure in atm is shown below:

P (Pa) = \frac {1}{101325} P (atm)

Given the value of pressure = 43,836 Pa

So,  

400 Pa = \frac {400}{101325} atm

Pressure = 0.0039 atm

w=0.0039\times 2\ atmL

Also, 1 atmL = 101.3 J

So,  

w=0.0039\times 2\times 101.3\ J=0.79014\ J (work is done by the system)

So,

\Delta U = 0\ J+0.79014\ J =0.79014\ J
