If a balloon containing 3000ll of gas at 39°c and 99 kpa rises to an altitude where the pressure is 45.5 kpa and the temperature is 16°c, the volume
of the balloon under these new conditions would be calculated using the following conversion factor ratios:

Molten iron fills a mould, which has a volume of 200 cm cubed. calculate the volume when the iron cools and solidifies. molten iron has a density of 7.0g/cm cubed. in its solid state, iron has a density of 8.0g/cm cubed.
