1.	A sample of a gas occupies 650.0 cm at 100^@C. At what temperature the gas will occupy a volume of 1050.0 cm^3if the pressure is kept constant ?
Answer» Solution :In the present case, `V_1 = 650.0 cm^3 "" V_2 = 1050.0 cm^3` `T_1 = 100^@C = 100 + 273 = 373 K, "" T_2` = ? The PRESSURE remains constant during expansion. Hence, ACCORDING to Charles. law `V_1/T_1 = V_2/T_2` or `T_2 = (V_2 T_1)/(V_1)=(1050.0 xx 373)/(650.0)= 602.5 K` Hence, the required TEMPERATURE is `602.5 - 273 = 329.5^@C`.
