1.	A sample of helium has a volume of500 cm^3at 373 K. Calculate the temperature at which the volume will become 260 cm^3 . Assume that the pressure is constant.
Answer» SOLUTION :Given that, `V_1 = 500 cm^3 , ""V_2 = 260 cm^3`, `T_1 = 373 K, "" T_2` = ? Since pressure remains CONSTANT, hence, according to Charles. law, we have `V_1/T_1 = V_2/T_2` or `T_2 = (V_2 T_1)/(V_1) =(260xx 373)/(500) = 194 K` Hence, the required TEMPERATURE is 194 K.
