When water is boiled under a pressure of 2.00atm, the heat of vaporization is 2.20×106J/kg and the boiling point is 120∘C. At th

Vikki [24]

Answer:

2033219.05 J

Explanation:

V = Volume

P = Pressure = 2 atm

m = Mass of water = 1 kg

$L_v$ = Heat of vaporization = $2.2\times 10^6\ J/kg$

Work done in an isobaric system is given by

$W=-P\Delta V\\\Rightarrow W=-2\times 101325\times (1\times 10^{-3}-0.824)\\\Rightarrow W=166780.95\ J$

Work done is 166780.95 J

Change in internal energy is given by

$\Delta U=Q-W$

Heat is given by

$Q=mL_v\\\Rightarrow Q=1\times 2.2\times 10^6\\\Rightarrow Q=2.2\times 10^6\ J$

$\Delta U=2.2\times 10^6-166780.95\\\Rightarrow \Delta U=2033219.05\ J$

The increase in internal energy of the water is 2033219.05 J

What is a physical property of matter

lyudmila [28]

ANSWER: B

EXPLANATION: There are four natural states of matter: Solids, liquids, gases and plasma. The fifth state is the man-made Bose-Einstein condensates. In a solid, particles are packed tightly together so they don't move much.
