Question

If it is estimated that 75 percent of electricity consumed by the heater is transferred to the water as heat, determine the local atmospheric pressure in that location

Expert Solution

Step 1

First, we calculate how much thermal energy (heat) was transferred to the water:

Knowing that all heat (Q) was used in making 1.19 kg of water boil (liquid to gas), we can find what is the latent heat of this change of state (vaporization):
