If the volame ofa gas coetainer at 32°c changes froem 1.55 l to 753 ml, what will the final temperature be? assume the pressure doesn't change and the amount of gas in the coatainer doesn't change. remember that there are 1,000 ml in 1 l. o a. 149°c ob. 353 c oc. 273c o d.-125 c oe none of the above.

Answer : The final temperature of gas will be, 149 K

Explanation :

Charles' Law : It is defined as the volume of gas is directly proportional to the temperature of the gas at constant pressure and number of moles.

or,

where,

= initial volume of gas = 1.55 L

= final volume of gas = 753 ml  = 0.753 L

= initial temperature of gas =

= final temperature of gas = ?

Now put all the given values in the above formula, we get the final temperature of the gas.

Therefore, the final temperature of gas will be, 149 K

out of these options:

ability to burn paper

pure sodium reacting violently with water

the boiling point of water

helium does not tend to react with anything

i would say this is a physical property:

helium does not tend to react with anything

why? :

i said helium does not tend to react with anything because well, it reacts to ! but ability to burn paper, pure sodium reacting violently with water, & the boiling point of water are chemical or

physical properties: the properties of a substance that can be observed without changing the chemical makeup of the substance

chemical properties: properties of a substance relating to the chemical nature and reactivity of the substance

1. they vary with a higher number because boiling is way hotter than melting
