An ideal monatomic gas expands isobarically, doubling the volume, from a state A to state B. It is then compressed isothermally

from state B to state C and finally cooled at constant volume until it returns to state A. No gas is allowed to enter or escape during the any of the processes.
a) Draw a PV diagram for this cycle.

b) How many atoms are in the gas?

c) Is the cycle a heat engine or pump?

d) If the cycle is a heat engine, what is the efficiency of the cycle. If the cycle is a heat pump, what is the coefficient of performance?

B because I just think it’s the right answer because drawing a PV diagram for this cycle is the best answer even though it might be a stupid so I would not pay attention to my response because I’m just getting this for points but let me know if it is the right answer because right now I’m just guessing.

WheN a car is driven some distance the air pressure in the tyre increases,why?
KatRina [158]
Over the course of a long drive, as a result of alternating between braking and acceleration and of course steering, tires get heated up. When this happens, the air within the tires gets heated up, causing the air within the tire to expand. This expanding air exerts force on the tire from inside thus increasing tire pressure.

PLS HELP MEEEE (NO LINKS PLEASE)
Brums [2.3K]

Answer:

Gamma rays occupy the short-wavelength end of the spectrum; they can have wavelengths smaller than the nucleus of an atom. Visible light wavesare one-thousandths the width of human hair--about a million times longer than gamma rays. Radio waves, at the long-wavelength end of the spectrum, can be many meters long.

When the plutonium bomb was tested in New Mexico in 1945, approximately 1 gram of matter was converted into energy. Suppose anot
gayaneshka [121]

Answer:

The value is E =  1.35 *10^{14} \ J

Explanation:

From the question we are told that

    The mass of matter converted to energy on first test is  m  =  1 \  g  = 0.001 \  kg

    The mass of matter converted to energy on second test m_1 =  1.5 \  g = 1.5 *10^{-3} \ kg

    Generally the amount of energy that was released by  the explosion is  mathematically  represented as  

         E =  m * c^2

=>       E =  1.5 *10^{-3}  * [ 3.0 *10^{8}]^2

=>       E =  1.35 *10^{14} \ J
