Answer:

29 mL

Explanation:

Step 1: Given data

Volume of water inside the graduated cylinder: 35 mL

Volume of the water after placing the keys: 64 mL

Step 2: Calculate the volume of the keys

The rise in the level of the water is due to the volume of the keys. We can find the volume of the keys by subtracting the final volume to the initial volume.

V(keys) = 64 mL - 35 mL = 29 mL

A balloon is filled with 2000 mL of air at a pressure of 2 atm. What is the volume of the balloon if the pressure is
artcher [175]

Answer:

800mL

Explanation:

Using Boyle's law which states that the volume of a given mass of gas is inversely proportional to the pressure, provided temperature remains constant

P1V1= P2V2

P1 = 2 atm, V1 = 2000mL ,

P2 = 5atm , V2 = ?

2 × 2000 = 5 × V2

Divide both sides by 5

V2 = 4000 ÷ 5

V2 = 800mL
