A balloon is inflated to a volume of 2.50 L inside a house that is kept at 24 °C. Then it is taken outside on a very cold winter day. If the temperature outside is -25 °C, what will be the volume of the balloon when it is taken outside? Assume that the quantity of air in the balloon and its pressure both remain constant.

(a) (248/297) x 2.50 L;

(b) (297/248) x 2.50 L;

(c) 248/(297 x 2.50) L;

(d) 297/(248 x 2.50) L.
