A cylinder, which is in a horizontal position, contains an unknown noble gas at 4.00 × 10 4 Pa 4.00×104 Pa and is sealed with a

massless piston. The piston is slowly, isobarically moved inward 16.3 cm, 16.3 cm, which removes 1.50 × 10 4 J 1.50×104 J of heat from the gas. If the piston has a radius of 30.5 cm, 30.5 cm, calculate the change in the internal energy of the system Δ U ΔU .

Answer:

-13094.55179 J

Explanation:

Q = Heat = -1.5\times 10^{4}\ J

P = Pressure = 4\times 10^4\ Pa

\Delta V = Change in volume = \pi r^2\times -h(negative because it is decreasing)

h = Height = 16.3 cm

r = Radius = 30.5 cm

Entropy is given by

\Delta U=Q-W

Work done is given by

W=P\Delta V\\\Rightarrow W=4\times 10^4\times (\pi 0.305^2\times -0.163)

\Delta U=-1.5\times 10^{4}-(4\times 10^4\times (\pi 0.305^2\times -0.163))\\\Rightarrow \Delta U=-13094.55179\ J

The change in the internal energy of the system is -13094.55179 J

Increasing the concentration and increasing the temperature both increase reaction rates based on which physical phenomenon? 1.

You can deal with this question using the collision theory, which states that the chemical reactions occur when particles collide with enough energy to reach the Activation Energy.

The velocity of the particles is related with the temperature. At higher temperatures,  higher velocities and higher frequency of collisions.

Also, at higher concentration (more particles is a same volume) the number of collisions will increase.

Then, hIgher concentration and higher temperature will increase the frequency of the molecular collisions..

Then, the answer is the proposal #1: "<span>increasing the frequency of molecular collisions"</span>

How is a plant able to cycle matter through the processes of cellular respiration and photosynthesis?
MissTica

The carbon cycle refers to the processes by which carbon in the biosphere is recycled. Photosynthesis sucks carbon dioxide out of the atmosphere, while cellular respiration releases it into the environment. Photosynthesis is the process by which solar energy reaches a plant and is converted into glucose.

<u>How photosynthesis and cellular respiration are similar:</u>

<em>Photosynthesis</em> is a method by which plants and other organisms transform light energy into chemical energy, which is then released to fuel the organism's metabolic activities through<em> </em><em>cellular respiration.</em>
