Question

The volume of a gas (a) is directly proportional to temperature expressed in Celsius scale (b) is zero at O = C (c) is inversely proportional to kelvin temperature (d) changes by V 0 [273.I for every 1 °C rise in temperature, where V_{0} is the temperature at 0 °C ni​

Answer 1

Answer:

The volume of a given gas sample is directly proportional to its absolute temperature at constant pressure (Charles's law). The volume of a given amount of gas is inversely proportional to its pressure when temperature is held constant (Boyle's law).

Answer 2

Explanation:

Vi/Ti=Vf/Tf

This is a direct relationship between volume and temperature, so you have to re-write the equation to solve for your desired variable. You are given:

Vi _initial volume) = 500mL

Ti (initial temperature) = 20.0 C

Tf (final temperature) = 60.0 C

So rewriting to solve for the final volume, we get

(Vi/Ti)(Tf)=Vf

Change your units to the appropriate SI units, volume is in liters and temperature is in kelvin. To convert from C-K, add 273.15 and from mL-L, divide mL by 1000.

500.0 mL = 0.5 L

60.0 C = 333.15 K

20.0 C = 293.15 K

Now plug into the equation that I derived and you get

(0.5L/293.15K)(333.15K)= 0.5682 L or 568.2 mL of gas.

This shows us a perfectly direct relationship between volume and temperature, with the initial and final volume-temperature ratios being equal.
