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.

Heat required to raise the temperature of a given system is
here we know that
m = mass
s = specific heat capacity
= change in temperature
now as we know that
mass of wood = 5 kg
mass of aluminium pan = 2 kg
change in temperature = 45 - 20 = 25 degree C
specific heat capacity of wood = 1700 J/kg C
specific heat capacity of aluminium = 900 J/kg C
now here we will find the total heat to raise the temperature of both
So heat required to raise the temperature of the system is 257500 J
