A balloon filled with gas is heated from 30.0°C to 197.0°C at constant pressure. If the original volume of the balloon was 1.560 L, what is the volume (in L) of the gas after heating?
A) 0.238 L
B) 1.02 L
C) 1.01 L
D) 2.42 L
E) 10.2 L

Using the formula for the relationship between volume and temperature at constant pressure:
V2 = V1 x (T2/T1)
where V1 = 1.560 L, T1 = 30.0°C + 273.15 = 303.15 K, and T2 = 197.0°C + 273.15 = 470.15 K.

V2 = 1.560 L x (470.15 K/303.15 K) = 2.42 L

Therefore, the volume of the gas after heating is 2.42 L, which is choice (D).
