What is the correct equation for the conservation of energy that represents this situation? (∑E_initial = ∑Ef_inal)
∆E_p = GPE

Ek + Ep = GPE

Ek = GPE + Ep

Ek + GPE = Ep

1

What is the correct equation for the conservation of energy that represents this situation? (∑E_initial = ∑E_final)
∆Ep = GPE

GPE = Ek + Ep

GPE = Ep

GPE + Ek = Ek + Ep

GPE + Ek = Ep

1

What is Internal Energy (U) of the molecules inside an object?

Breaking the chemical bonds to change into gas state.

The average kinetic energy of all the molecules inside an object.

The addition of the Potential Energy between molecules and their random kinetic energy.

Is the energy due to random motion (vibrations and rotations) of a molecule.

1

What is Temperature?

The average kinetic energy of all the molecules inside an object.

The addition of the Potential Energy between molecules and their random kinetic energy.

Is the energy due to random motion (vibrations and rotations) of a molecule.

Breaking the chemical bonds to change into gas state.

Where do we have the highest random Kinetic Energy in one molecule?

Liquid

Gas

Solid

1

What do we need in order to change from gas to liquid state?

Remove energy from the mass

Add energy to the mass

1

There are 3 ways to transfer heat, which way is used to heat up the pan?

Conduction

Convection

Radiation

1

This picture illustrates the concept of...

Thermal Equilibrium

Thermal Energy

Radiation

Boiling Point of water

1

What is the definition of HEAT?

Energy to change the state of matter

Transfer of Thermal Energy

Average random kinetic energy

Energy to raise the temperature of the object

What is the equation to increase the temperature of a gas

Q = mL

Q = mc∆T

1

Why does the horizontal line on 0ºC shorter than on 100ºC?

Line on 0ºC needs large amount of energy to change of state.

Line on 100ºC needs large amount of energy (related to time) to change of state.

Horizontal lines do not represent changes betwen states of matter.
