First look at the things that need to be converted $35.9 ^@"C" = "(35.9 + 273.15) K" = "309.0 K"$ $"25.5 kPa = 0.2467 atm"$ $"500 mL = 0.500 L"$...
1 Answers 1 viewsGiven $Pprop1/V$, $P_1V_1=P_2V_2$, and the great advantage of this proportionality is that we can use unorthodox units of pressure and volume, i.e. $"psi, pints, atmosphere, gallons"$ so long as we...
1 Answers 1 viewsThis is an example of a problem. $color(blue)(|bar(ul((P_1V_1)/T_1 = (P_2V_2)/T_2|)$ We can rearrange this formula to get $V_2 = V_1 × P_1/P_2 × T_2/T_1$...

1 Answers 1 viewsholds that $P_1V_1=P_2V_2$ at constant temperature. And thus $P_2=(P_1V_1)/V_2=(1.2*atmxx8*mL)/(12*mL)=0.8*atm$. This decrease in pressure is reasonable, given that we have INCREASED the volume.
1 Answers 1 viewsThe idea here is that the volume and the temperature of a gas have a direct relationship when the pressure and the number of moles of gas are being kept...
1 Answers 1 views$(P_1V_1)/T_1=(P_2V_2)/T_2$ You need to convert degC to Kelvin by adding 273: $:.(200xx25)/298=(250xxV_2)/273$ $:.V_2=(200xx25xx273)/(298xx250)$ $:.V_2=18.32"L"$

1 Answers 1 viewsEven without doing any calculations, you should be able to look at the information given and predict that the volume of the gas will increase after temperature is increased and...
