# How do you determine the volume if 1.5 atm of gas at 20° C in a 3.0 L vessel are heated to 30° C at a pressure of 2.5 atm?

?? The volume is presumably constant..........

You could have specified a gas in a PISTON, whose volume would decrease with increased pressure and increase with increased temperature, but this would not have adequately specified the problem.

You can use the combined gas law to determine the volume. The combined gas law equation is ( \frac{P_1 \times V_1}{T_1} = \frac{P_2 \times V_2}{T_2} ), where ( P_1 = 1.5 , \text{atm} ), ( V_1 = 3.0 , \text{L} ), ( T_1 = 20^\circ \text{C} + 273.15 = 293.15 , \text{K} ), ( P_2 = 2.5 , \text{atm} ), ( T_2 = 30^\circ \text{C} + 273.15 = 303.15 , \text{K} ). Solve for ( V_2 ).

When evaluating a one-sided limit, you need to be careful when a quantity is approaching zero since its sign is different depending on which way it is approaching zero from. Let us look at some examples.
