I'm looking at the barometer in my lab as i type this question. it says the pressure is 0.905 atm. what is this pressure express
Tcecarenko [31]
1 atm is equivalent to 760 torr.

To express 0.905 atm in torr, all you have to do is cross multiplication as follows:
1 atm ................> 760 torr
0.905 atm .........> ?? torr
pressure = (0.905 * 760) / (1) 
pressure = 687.8 torr

lubasha [3.4K]

Answer:

2.837% less than actual value.

Explanation:

Based on given information let's calculate our value.

S = Vxt = 331m/s x 5s = 1655m, that is the total distance that sound would travel in 5 seconds.

1mile = 1609.34meters.

percentage error is.

\frac{actual-calculated}{actual} *100 = \frac{1609.34-1655}{1609.34} *100 = -2.83%

negative indicates less than actual value.

In a rigid container, as the temperature of a gas decreases, the pressure of the gas will decrease. t f
Sergio039 [100]
The answer is true: the pressure of a gas will decrease as temperature decreases in a rigid container.

This is one of the central gas laws called the Gay-Lussac law that states for a given gas at a constant volume, the pressure of the gas is directly proportional to its temperature. We also know that as temperature reduces, so too does molecular interaction. Increased temperature results in increased pressure, and decreased temperature therefore results in decreased pressure.
