3) What amount of heat will change 78g liquid water at 30 o C to vapor at 200 o C?

Sagot :

Assuming we’re not freezing the water into ice, the specific heat capacity of water is 4.2 J/g°C.

78* 30°C = 2340g°C

4.2J/g°C * 2340°C = 9828Joules or98.2 kJ.

How many Joules are required to convert one gram of 100 °C water into steam?

The heat of vaporization for water at its boiling point of 100 oC is 2260 J g-1. This means that 2260 J of heat must be absorbed by the water in order for it to change from 1 g of water at 100 oC to 1 g of steam at 100 oC.

What does the chemical symbol H mean?

The amount of heat released or absorbed during a reaction that takes place under constant pressure is referred to as the enthalpy change. It has the sign H, which can be interpreted as "delta H."
