Explanation:
A reference point is a place or object used for comparison to determine if something is in motion. An object is in motion if it changes position relative to a reference point
Answer:
3040 torr
Explanation:
Applying,
PV = P'V'..................... Equation 1
Where P = Initial Pressure, V = Initial volume, P' = Final pressure, V' = Final volume.
Make P' the subject of the equation
P' = PV/V'................. Equation 2
From the question,
Given: P = 760 torr, V = 56.2 L, V' = 56.2/4 = 14.05 L
Substitute these values into equation 2
P' = (56.2×760)/14.05
P' = 3040 torr
Answer:
Explanation:
The difference of pressure is given by gauge pressure:
Lubricant is a type of oil. It smoothes surfaces. Meaning anything rubbing against the other object wont produce enough heat, which is what creates friction. Its an ideal tool to use for a lot of things.
I hope this helps :)
