Question

An empty bottle, at 25°C,has a volume of 2 L. Whatwill the new volume be if youput it in a freezer at -4°C?

Answer 1

ANSWER

1.8L

EXPLANATION

Something important to have in mind in questions like these is that temperature and volume increase and decrease together, so higher temperature = higher volume, and the opposite is also true. The equation I used was:

V1/T1 = V2/T2

V stands for the volume

T stands for the temperature (this one must be in Kelvin, so always think in add the temperature to 273K)

2/298 = V2/269

V2 = 1.8L
