Charles law

a balloon of helium was put in the freezer at -23°c. its volume at this temperature was 2.5 liters. it was removed from the freezer. eventually, it reached a temperature of 177°c. what would its volume be at this temperature? (neglect any force used to stretch the rubber balloon.) asap

a. 1.4
b. 45000
c. 4.5
d. 0.22

Answer : The volume at will be, (C) 4.5 L

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 = 2.5 L

= final volume of gas = ?

= initial temperature of gas =

= final temperature of gas =

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

Therefore, the volume at will be, (C) 4.5 L

the density(ratio between mass and volume as m/v) decreases from top to bottom in periodic table group as the size increases and nuclear charge decreases. but in periods density increases from left to right as atom size decreases and nuclear charge increases.

some sources quote the lethal dose, for an average 170lbs opiate-naive individual is between 75 and 375 mg
