Re: Thermodynamics B/C

What is the heat energy required to completely vaporize 110g of water beginning at 0°C? (The heat capacity of water is 4.2 J/g⋅K and the ΔH
vaporization of water is 2260 kJ/kg

$100 K * 4.2 \frac{J}{g*K} * 110 g + 2260 J/g * 110 g$

Re: Thermodynamics B/C

All right! When heat flows through a wall, what kind of process is that?

Re: Thermodynamics B/C

Diathermic, but I guess I could've been more specific with the question
The zeroth law of thermodynamics allows us to define what quantity?

What is the common heat engine cycle used for most power plants?
