The Heating Curve

Question 1

What is kinetic energy

Answer 1

The energy an object possesses due to it’s movement

Question 2

What is temperature

Answer 2

A measure of the average kinetic energy of particles,

given in a Substance

Question 3

What is melting point

Answer 3

The tempreture at which the solid phase and liquid phase exits in equilibrium

The solid changes into a liquid

Question 4

What is boiling point

Answer 4

The temperature at which the
vapor pressure of a substance is equal to the atmospheric
pressure. The liquid changes into a
gas.

Question 5

NUMBER1

As you heat ice
What happened to the energy supplied

And what happens to the particles

Answer 5

As you heat ice the energy supplied is used to increase the kinetic energy of particle

This results in particles to vibrate faster

Question 6

NUMBER2

Continuously hearing ice eventually reaches a point where energy supplied is not used to increase kinetic energy

What is energy used for

Answer 6

Yeh energy is used to break up the intermolecular forces holding the particles together

Question 7

NUMBER2

A) When the IMF break what happened to the particles

B) what phase is present here

C)Describe the change in temperature
And what is the reason for this

E) what point is this known as

Answer 7

A)The particles separate resulting in a a loose packing which is the liquid phase

B) both the liquid and solid

C) temperature remains constant as kinetic energy is not increasing

E) the melting point

Question 8

NUMBER3

One all the ice is melted and only the liquid phase is present

What happens to the energy supplied
What does this result in

Answer 8

The energy supplied is used increase the kinetic energy of particles
Thai results I’m an increase in temp

Question 9

NUMBER4

After continuously heating after the liquid phase

A) what happens to the energy supplied

B) describe the temperature

C) describe what happens to the particles

D)what phase is present

E) what point is this one on as

Answer 9

A)energy supplied is used to break the inter molecular forces

B) the temperature remains constant

C)this results in particles being further apart which is a gaseous State

D) both liquid and gas

E) Boiling point

Question 10

NUMBER5

What happened after the boiling point

Answer 10

All water has evaporated

Only the gaseous phase is present
