1. Calculate the amount of heat needed to convert 190.0 g of liquid water at 18 °C to steam at 100°C. (two calculations)
2. Calculate the amount of heat needed to convert 96 g of ice at -24 °C to water at 28 °C. (figure out how many steps first and be sure to use correct specific heats)
3. Calculate the amount of heat released to the environment as 245 g of steam at 140 °C cooled to -15 °C.
