Question #8fca6
1 Answer
Explanation:
Your tool of choice here will be the combined gas law equation, which looks like this
color(blue)(ul(color(black)((P_1V_1)/T_1 = (P_2V_2)/T_2)))
Here
P_1 ,V_1 ,T_1 are the pressure, volume, and absolute temperature of the gas at an initial stateP_2 ,V_2 ,T_2 are the pressure, volume, and absolute temperature of the gas at a final state
In your case, you know that
T_1 = "273 K"
and that the pressure and volume of the gas must double as a result of the increase in temperature. You can say that
P_2 = 2 * P_1" " and" "V_2 = 2 * V_1
Rearrange the combined gas law equation to solve for
(P_1V_1)/T_1 = (P_2V_2)/T_2 implies T_2 = P_2/P_1 * V_2/V_1 * T_1
Plug in your values to find
T_2 = (2 * color(red)(cancel(color(black)(P_1))))/color(red)(cancel(color(black)(P_1))) * (2 * color(red)(cancel(color(black)(V_1))))/color(red)(cancel(color(black)(V_1))) * "273 K" = color(darkgreen)(ul(color(black)("1090 K")))
The answer is rounded to three sig figs.
