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

Feb 5, 2017

To calculate the heat required:

#### Explanation:

$Q = {Q}_{\text{melting" + Q_"liquid" + Q_"evaporation" + Q_"steam}}$
Q = L_fm + mc∆T + L_vm + mc∆T
$Q = \left(3.3 \cdot {10}^{5}\right) \left(0.100\right) + \left(0.100\right) \left(4180\right) \left(100\right) + \left(2.3 \cdot {10}^{6}\right) \left(0.100\right) + \left(0.100\right) \left(2000\right) \left(115 - 100\right)$
$Q = 33000 + 41800 + 230000 + 1000$
$Q = 305 800 J$

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