Transcribed Image Text:**Calculating Heat Required for Phase Change: Water to Steam**
To determine the heat required to convert 10.0 g of water at 100°C to steam at 100.0 °C, we need to consider the energy needed for the phase change from liquid to gas.
**Given Data:**
- Mass of water = 10.0 g
- Temperature = 100°C
- Specific heat of water = 1.00 cal/(g × °C)
- Heat of fusion (melting ice) = 80.0 cal/g (not required here)
- Heat of vaporization = 540.0 cal/g
**Calculation:**
Only the heat of vaporization is needed as the water is already at 100°C, the boiling point. The energy required is calculated using the formula:
Q = m × Hv
where:
- Q = heat energy (calories)
- m = mass of the substance (g)
- Hv = heat of vaporization (cal/g)
**Substitute the values:**
Q = 10.0 g × 540.0 cal/g = 5400.0 cal
Therefore, 5400.0 calories of energy are required to convert 10.0 g of water at 100°C to steam at 100°C.
