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;

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;

V₂ = 682mL

Answer:
The answer is Observation.
For you to observe the things around you then you need to use all your sense organs....
1) baking soda (NaHCO₃ - sodium bicarbonate) is white, solid, crystalline salt or <span>appears as a fine powder.
2) vinegar is mixture of acetic acid (CH</span>₃COOH) and water (H₂O). Vinerar is colourless liquid with <span>sour taste and pungent smell.
3) Chemical reaction: </span>NaHCO₃ + CH₃COOH → CH₃COONa + CO₂ + H₂O.
Jane should see bubbles of carbon(IV) dioxide.
4) sodim acetate (CH₃COONa) is solid and carbon dioxide (CO₂) is gas.
5) Jane can put burning match over reaction, the fire on the match is going to put out because of carbon dioxide.
