One day, when the temperature and pressure were 300 K and 760 mm, a mass of gas had a volume of 1200 ml. On the next day, the volume had changed to 1218 ml while the pressure was the same. What was the temperature on the next day?

Prashant Kotian · Accepted Answer

Correct answer: B. Since pressure is constant, V1 / T1 = V2 / T2. Given: V1 = 1200 ml, T1 = 300 K, V2 = 1218 ml. T2 = (V2 * T1) / V1 = (1218 * 300) / 1200 = 1218 / 4 = 304.5 K.
