Sixth-grade students conduct a laboratory experiment investigating the flow of thermal energy. They place a sealed plastic bag f

illed with water at 60°C into a beaker filled with an equal amount of water at 80°C. They then put the beaker with the plastic bag in an insulated container.
Based on the flow pattern of thermal energy, what can students predict will most likely happen in about an hour?



A. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in the beaker will be 60°C and the temperature of the water in the plastic bag will be 80°C.


B. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in the plastic bag will be 80°C and temperature of the water in the beaker will be 60°C.


C. Thermal energy will flow from the warmer water in the beaker to the cooler water in the plastic bag so that the temperature of the water in both the plastic bag and the beaker will be 70°C.


D. Thermal energy will flow from the cooler water in the plastic bag to the warmer water in the beaker so that the temperature of the water in both the beaker and the plastic bag will be 70°C.

Why would it be more difficult to inject the nucleus of uranium with a proton?
nasty-shy [4]

Answer:

Because there are already 92 protons in the

uranium nucleus, combining their repulsive power to reject the one new one. However, if the energy of the incoming proton is sufficiently great, then at extremely close distance, the uranium nucleus will attract the proton and draw it into the nucleus. This is called the strong force.

Aluminum oxide (Al2O3) is a widely used industrial abrasive (known as emery or corundum), for which the specific application dep
ivanzaharov [21]

Answer:

On the Moh's scale of hardness, aluminum oxide is positioned just below to diamond due to which it is considered as one of the hardest known compounds. This also shows that the compound exhibit an enormous amount of lattice energy, as to transform the oxide into its constituent ions, the energy is required to overcome.  

Based on the chemical formula of the compound, that is, Al2O3, it is shown that the ions of Al3+ and O2- are kept close due to the activity of the strong electrostatic ionic bonds. The electrostatic forces and the ionic bonding between the ions are extremely robust due to the presence of the ions high charge density. Therefore, to dissociate the bonds, an enormous amount of energy is needed, and at the same time, a high amount of lattice energy is present.
