Question

(1 point)
Responses

The particles will have the same average kinetic energy and the same temperature during boiling.

The particles will lose kinetic energy and increase temperature during boiling.

The particles will have the same average kinetic energy and a decrease in temperature during boiling.

The particles will lose kinetic energy and decrease temperature during boiling.

2.
What does temperature measure? (1 point)
Responses

the empty space between the particles

the average kinetic energy of the particles

the heat of the particles

the total energy of the particles


3.
Which is the best interpretation of the two flat portions of the graph?

(1 point)
Responses

These show where kinetic energy is increasing.

These show where changes of state are occurring.

These show where temperature is 0ºC.

These show where thermal energy does not exist.

Answer 1

The correct option is;

a. The particles will gain a large amount of kinetic energy

Step-by-step explanation:

As the water temperature reaches 100°C, which is the boiling point for water at atmospheric pressure, the continued heating is then used to break up the strong inter molecular forces between molecules of the water such that the individual molecules are free to move about and due to the high temperature, have gained considerable amount of kinetic energy for the to rise to appreciable height and to also spread.

The heat which converts water into steam is called latent heat as during the boiling phase, the temperature of the water remains constant.
