If a liter of water is heated from 20 degrees c to 50 degrees c what happens to its volume

The volume increases by 10.3 mL.

Explanation:

This is not an easy question to answer, because water expands at different rates depending on the temperature.

However, we can use the known densities of water at these temperatures.

(a) Calculate the mass of 1 L of water at 20 °C.

The density of water at 20 °C is 0.998 20 g/mL.

(b) Calculate the volume at 50 °C.

The density of water at 50 °C is 0.988 03 g/mL.

∴ The volume increases by 10.3 mL.

the reaction mixture contains some ammonia, plus a lot of unreacted nitrogen and hydrogen. the mixture is cooled and compressed, causing the ammonia gas to condense into a liquid. the liquefied ammonia is separated and removed. the unreacted nitrogen and hydrogen are then recycled back into the reactor .
