Question

How much heat is required to take 100. g of ice at 0.00 C to steam at 115 C?

Answer 1

To calculate the heat required:

Explanation:

`Q = Q_"melting" + Q_"liquid" + Q_"evaporation" + Q_"steam"`
`Q = L_fm + mc∆T + L_vm + mc∆T`
`Q = (3.3 * 10^5)(0.100) + (0.100)(4180)(100) + (2.3 * 10^6)(0.100) + (0.100)(2000)(115-100)`
`Q = 33000 + 41800 + 230000 + 1000`
`Q = 305 800 J`

A heat curve graph may be necessary to visualize this problem.
