When a substance goes from being a liquid to a gas it evaporates, or boils away. Think of boiled eggs.
Answer:
They are heavy metals.
Explanation:
Heavy metals are generally defined as metals with relatively high densities, atomic weights, or atomic numbers.
The process which has taken place is called CRYSTALLIZATION.
Generally, crystallization is the process by which solid crystals are precipitated from solution. Crystallization can also occur when a crystal melt or when a crystal get deposited directly from a gas, although these cases are rarer compare to crystals forming from solutions.
Answer: The volume of sample at 400 K is 
Explanation:
Charles' Law: This law states that volume is directly proportional to the temperature of the gas at constant pressure and number of moles.
(At constant pressure and number of moles)
where,
= initial volume of gas =
= final volume of gas = ?
= initial temperature of gas = 360 K
= final temperature of gas = 400 K
Putting in the values we get:

Thus volume of sample at 400 K is
