Text Solution

Solution : Let the initial volume be x , `V_1=x` <br> `V_2` = ? <br> `T_1`= 273 K <br> `T_2=273^@C` = 273+273 =546 K <br> According to Charles.s law, `V_1/T_1=V_2/T_2` <br> `x/273=V_2/546` <br> `V_2=(546xx x)/273` <br> `V_2`= 2x <br> Thus, it is proven that the volume of any gas at `273^@C` is twice its volume at 273 K, at constant pressure.
