Practice problem
High Specific Heat (Water) — Properties & Examples
For the problem below, assume that you have 1 kg of each substance listed in the table. The units of energy for all values in this table are Joules (J).

The table above shows how much energy is needed to heat up four common substances (water, iron, salt, and ammonia) by only 1°C.
Use this information to answer the question below.
Which substance has the highest specific heat (i.e., requires the most energy to heat up)?
