Need help with some chem equations 1. While diving under 3.7 atm of pressure, a gas bubble of 25 mL was found when release at surface at 1 at how big did the bubble get

2. a blue 3 L balloon at 25c was moved to a temperature of 38c what is new volume

3. 1.72 L of gas at STP was transferred to a new container with temps 18c and volume of 3.1 L what is new pressure

An observation that requires measurement is called quantitative observable or qualitative
