We can use the equation q = m × Cg × ΔT to describe it
Note: the heat capacity of gaseous water, Cg = 2.00 J/g°C is different from solid or liquid
Calculate the heat that would have been required to heat the 300g of water used in the data table from its starting temperature as a liquid of 100°C to its final temperature at 120°C.
