# What amount of energy is used when 33.3 grams of ice at 0.00 °C is converted to steam at 150.0 °C?

##### 1 Answer

#### Explanation:

The answer is

We need to determine the total energy required to go from ice to water, and then from water to vapor - the phase changes underwent by the water molecules.

In order to do this, you'll need to know:

**Heat of fusion of water**:

**Heat of fusion vaporization of water**:

**Specific heat of water**:

**Specific heat of steam**:

So, the following steps describe the overall process:

**1**. Determine the heat required to convert

**2**. Determine the heat required to go from water at

**3**. Determine the heat required to convert

**4**. Determine the heat required to go from

Therefore, the total heat required is
