What happens to the particles in water as the water is heated and turns to vapor
2 answers:
Answer: The particles move more quickly.
Explanation:
Kinetic energy is the energy possessed by an object by virtue of its motion. It is determined by the equation:
From above, it is visible that kinetic energy is directly related to the temperature of the system. So, if temperature is more, average kinetic energy of the system is more and movement of particles is more.
Thus the particles in water are heated, they gain kinetic energy and hence move more quickly.

Answer:
The kinetic energy is: 50[J]
Explanation:
The ball is having a potential energy of 100 [J], therefore
PE = [J]
The elevation is 10 [m], and at this point the ball is having only potential energy, the kinetic energy is zero.
In the moment when the ball starts to fall, it will lose potential energy and the potential energy will be transforme in kinetic energy.
When the elevation is 5 [m], we have a potential energy of
This energy is equal to the kinetic energy, therefore
Ke= 50 [J]
