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

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.

What is the equation to increase the temperature of a gas

Q = mL

Q = mc∆T

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.
