Question

fill in the missing words
the pressure of a gas is 1.00 atm at 25 degrees celsius. when the gas is heated to 100 degrees celsius, the pressure changes to atm.

Explanation:

Step1: Convert temperatures to Kelvin

$T_1 = 25 + 273.15=298.15$ K, $T_2=100 + 273.15 = 373.15$ K

Step2: Apply Gay - Lussac's Law ($\frac{P_1}{T_1}=\frac{P_2}{T_2}$)

$P_2=\frac{P_1T_2}{T_1}$

Step3: Substitute values

$P_2=\frac{1.00\times373.15}{298.15}\approx1.25$ atm

Answer:

1.25
