Question

Which statement most accurately describes Charles’s law?

A. The volume of a gas varies directly with its temperature at constant pressure.

B. The volume of a gas varies inversely with its temperature at constant pressure.

C. The pressure on a gas varies directly with its temperature at constant volume.

D. The pressure on a gas varies inversely with its temperature at constant volume.

Answer 1

A is the answer for sure i got it right after working it out.

Answer 2

.A.The volume of a gas varies directly with its temperature at constant pressure.

Explanation:

This law is expressed mathematically as;

V₁ /T₁ =V₂/T₂ where

V₁=initial volume

T₁=initial absolute temperature

V₂=final volume

T₂=final absolute temperature

The temperature is converted to Kelvin when doing calculations where;

0°c = 273 K

An application of this law in real world examples could be when a ball is left outside overnight it the cold, the ball shrinks a little in its volume due to decreased temperatures.
