600.0 mL of air is at 20.0 c what is the volume at 60.0
pogonyaev

682mL

Explanation:

Given parameters:

Initial volume of air = 600mL

Initial temperature = 20°C

Final temperature = 60°C

Unknown:

Final volume = ?

Solution:

To solve this problem, we apply Charles's law';

Charles's law states that "at constant pressure, the volume of a given mass of gas is directly proportional to its temperature. "

Mathematically;

   \frac{V_{1} }{T_{1} }  = \frac{V_{2} }{T_{2} }

V₁ is the initial volume  of air

T₁ is the initial temperature  of air

V₂ is the final volume  of air

T₂ is the final temperature of air

To proceed in solving this problem, we need to convert the given temperature to Kelvin;

T K = 273 + T°C

T₁  = 273 + 20 = 293K

T₂ = 273 + 60 = 333K

now input the parameters;

V_{2}  = \frac{V_{1} }{T_{1} }  x T_{2}  = \frac{600}{293 }  x 333

 V₂ = 682mL

andreyandreev [35.5K]
Cylinder A - Adding 25 grams raised the water level by roughly 3.2 mL

Cylinder B - Adding 25 grams raised the water level by roughly 2.8 mL

Cylinder C - Adding 25 grams raised the water level by roughly 3.5 mL

Calculate grams/mL (density)

A. 25 g/3.2 mL = 7.8125 g/mL = Iron
B. 25 g/2.8 mL = 8.9286 g/mL = Nickel
C. 25 g/3.5 mL = 7.1429 g/mL = Zinc

Hope I helped!
