2. carbon dioxide is in a steel tank at 20°c, 10 liters and 1 atm. what is the pressure on the gas when the tank is heated to 100°c? . 3. what temperature will 215 ml of a gas at 20°c and 1 atm pressure attain when it is subject to 1.5 atm of pressure? . 4. when the volume changes from 63.5 ml to 69.2 ml, what is the final pressure if the initial pressure was 735 mm hg pressure? . which laws were used on theese? desperate for . i totally suck at chemistry.

Explanation:

Carbon dioxide is in a steel tank at 20°C, 10 liters and 1 atm.

Volume of the gas = 10 L

1) Initial Pressure of the gas

Initial temperature of gas =

Final pressure of the gas, when volume remains constant =

Final temperature of the gas

(Gay Luassac's law)

1.27 atm is the pressure on the gas when the tank is heated to 100°C.

2) Initial Pressure of the gas

Initial temperature of gas =

Final pressure of the gas, when volume (215 mL) remains constant =

Final temperature of the gas

(Gay Luassac's law)

3)When the volume changes from 63.5 mL to 69.2 mL ,if the initial pressure was 735 mm Hg pressure.

Initial volume of the gas

Initial pressure of gas =

Final pressure of the gas,  =

Final volume of the gas

(Boyle's law)

The 674.4 mmHg was the final pressure when gas occupies 69.2 mL of volume.
