i just took this test and got it right
<u>Given:</u>
Pressure = 565 torr
<u>To determine:</u>
Corresponding pressure in atmospheres
<u>Explanation:</u>
Pressure is commonly expressed in units like:
Atmosphere (atm), Torr or mmHg
The SI unit is atm, where
760 torr = 1 atm
Thus, a pressure reading of 565 torr corresponds to:
565 torr * 1 atm/760 torr = 0.743 atm
Forming oxygen by bubbling fluorine through water.

Explanation:
Answer:
51 J
Explanation:
The air inside a bicycle tire pump has 27 joules of heat conducted away. By convention, when heat is released, it takes the negative sign, so Q = -27 J.
77.9 joules of work done are being done on the air inside a bicycle tire pump. By convention, when work is being done on the system, it takes the positive sign, so W = 77.9 J
We can calculate the change in the internal energy (ΔU) using the following expression.
ΔU = Q + W
ΔU = (-27 J) + 77.9 J
ΔU = 51 J
