(a). If the temperature of a substance is increased the density of it will also increased. The temperature is directly proportional to the density because the molecular activity of the substance will be affected by the temperature

(b). The mass of the substance doesn't at all. Because the amount of matter inside the substance cannot be affected by the temperature except that its water
