Question

Determine the amount of energy required (in MJ) to convert 45 g of ice, initially at a temperature of -15°C, to steam at 155°

Answer 1

Answer #1

There are five heats to consider:

q1 = heat required to warm the ice to 0.00 °C.

q2= heat required to melt the ice to water at 0.00 °C.

q3= heat required to warm the water from 0.00 °C to 100.00 °C.

q4= heat required to vapourize the water to vapour at 100 °C.

q5= heat required to warm the vapour to 155 °C.
