Answer:
true
Explanation:
Hotter things have more heat energy than colder things. That's because the atoms or molecules move around faster in hot things (red, right) than they do in cold things (blue, left). ... The more heat you supply, the faster the molecules move and the further apart they get.
The pressure (in atm) in a 5 L tank with 37.50 grams of oxygen gas at 350 K is 6.715 atm.
<h3>How do we calculate the pressure of gas?</h3>
Pressure of gas will be calculated by using the ideal gas equation as:
PV = nRT, where
P = pressure = ?
V = volume = 5 L
R = universal gas constant = 0.082 L.atm / K.mol
T = temperature = 350 K
n is the moles of gas and it will be calculated as:
n = W/M, where
W = given mass = 37.50 g
M = molar mass of oxygen = 32g/mol
n = 37.50/32 = 1.17 mol
On putting all these values, we get
P = (1.17)(0.082)(350) / (5) = 6.715 atm
Hence resultant pressure of the oxygen gas is 6.715 atm.
