Answer true
Explanation:
Boiling point, and temp. Can be a result of a change in concentration.
I hope you can understand this and i hope this helps.
<span>Speed increases with increasing temperature. Gas molecule speed follows the formula
v(average) = 8RT/(pi*M), where
M = molar mass (e.g., 0.002 kg/mole for hydrogen)
R = universal gas constant = 8.314472 J/(mole-degK)
T = temperature K
The ref. gives the derivation of this formula and other formulas for v(RMS) and v(most probable).</span><span>If u dont understand i can make it simpler just ask.</span>

Answer:
We are given:
Volume (V) = 0.25 L
Pressure (P) = 0.93 atm
Temperature (T) = 15.4°C OR 288.4 K
<u>Solving for the number of moles of CO₂:</u>
From the ideal gas equation:
PV = nRT
replacing the variables
0.93 * 0.25 = n (0.082)(288.4)
n = 0.00983 moles
<u>Number of molecules:</u>
Number of moles= 0.00983
number of molecules in 1 mole = 6.022 * 10²³
Number of molecules in 0.00983 moles = 0.00983 * 6.022 * 10²³
Number of molecules = 5.91 * 10²¹
