PLEASE HELP IM BEGGING Which object has the least thermal energy?
O A. 2 kg of liquid oxygen at -225°C
O B. 5 kg of oxygen gas at 30°C
O c. 5 kg of liquid oxygen at -225°C
D. 2 kg of oxygen gas at 20°C

Materials will have different energies associated with the electrons inside them. this is related to how strongly bound they are by their work function. if we sandwich a material with a very low energy between two materials with a high energy, we create a trap for an electron. if this trap is very narrow in one direction in comparison to the others, this is approximately a 1-dimensional box that confines the electron. what is the lowest energy of an electron in the box if the thinnest direction across the materials is 4.81 nm?
