The pressure gauges on two cylinders of equal volume both show the same pressure reading. Cylinder A is at 23 degrees Celsius and Cylinder B is at -10 degrees Celsius. What is a possible explanation for the same pressure reading?

Show and image of the mixtures or write them

The formula is (nh4)2co3

Those are different gas lawshere is a brief description of themcharles's law states that volume and temperature are directly proportional to each other as long as pressure is held constant.  boyle's law asserts that pressure and volume are inversely proportional to each other at fixed temperature.gay-lussac's law introduces a direct proportionality between temperature and pressure as long as it is at a constant volume.    source:
