the air pressure from the atmosphere measures 0.5atm at an altitude of 18,000 ft. How much pressure is this in pounds per square

Julli [10]

14.7lb/in²

Explanation:

This is a conversion problem from atm to pounds per square inch

Pressure is the combined force per unit area of substance on another.

Given pressure = 0.5atm

To solve this problem ;

Convert from atm to N/m² to pound per square inch

1 atm = 101325N/m²

0.5atm = 0.5 x 101325 = 50,662.5‬N/m²

now we need to convert to pound per square inch;

1N = 0.225lb

1m = 39.37in

Solving;

101325 N $x \frac{1}{m^{2} } x \frac{0.225lb}{1N } x \frac{m^{2} }{39.37in x 39.37in}$ = 14.7lb/in²

A gas that was cooled to 200 Kelvin has a volume of 65.8 L. If its initial volume was 132.4 L, what was its initial temperature?

Mandarinka [93]

Answer:

Initial temperature, T1 = 99.4 Kelvin

Explanation:

Given the following data;

Initial volume, V1 = 65.8 Litres
Final temperature, T2 = 200 Kelvin
Final volume, V2 = 132.4 Litres

To find the initial temperature (T1), we would use Charles' law;

Charles states that when the pressure of an ideal gas is kept constant, the volume of the gas is directly proportional to the absolute temperature of the gas.

Mathematically, Charles' law is given by the formula;

$\frac {V}{T} = K$
