Alchen [17]

Explanation:

$from \: boyle's \: law \\ P _{1} V _{1} = P _{2} V _{2} \\ 35 \times 11.2 = 64 \times V _{2} \\ V _{2} = \frac{35 \times 11.2}{64} \\ V _{2} = 6.125 \: L$

a gas has a volume of 2.00 at 323k and 3.00 ATM What would be the new volume if the temperature is changed to 273 K in the press

Ber [7]

Answer:

$V_2 = 5.07L$

Explanation:

$\frac{P_1 V_1}{T_1} = \frac{P_2 V_2}{T_2}\\V_2 = \frac{P_1 V_1 T_2}{T_1 P_2} = \frac{3.00atm \cdot 2.00L \cdot 273K}{323K \cdot 1.00atm} = 5.07L$
