University of Maryland - University College

Explain how the high specific heat capacity of water can affect the weather in coastal regions.
What is energy? What is work? List some examples of each.
If two objects, A and B, of different temperature come into direct contact, what is the relationship between the heat lost by one object and the heat gained by the other? What is the relationship between the temperature changes of the two objects? (Assume that the two objects do not lose any heat to anything else.)
What is heat capacity? Explain the difference between heat capacity and specific heat capacity.

so under the topic of periodic properties of homes, will be generally learning about the periodic table and how to use it to predict trends based on the number of protons in the nucleus as well as the number of electric. And so in the past, elements have been organized in a variety of ways, but now it is organized by increasing atomic number. And the periodic table became an incredibly useful tool for us to predict the properties of elements based on the number of electrons and protons that element has, and an important concept that will help us understand the periodic trends of elements. Is Thea effective nuclear charge, which is the true force that the protons in the nucleus will exert on the vans electrons. Considering the shielding effect caused by electrons and lower energy level and as a result of the effective nuclear charge, we can generally determined a trend for atomic and ionic radia where the atomic radia will increase going down a group and decrease across a period. And in the case I Ionic radio, the Catalans will generally have a smaller radio and an ions will have a larger ingredient and we can also use the periodic table and the concept of valence electrons to describe trends in organization energy, which is the energy required to remove an electron from an and generally the organization. Energy decreases going down a group and increases across a period. And like atoms, we can also determine the electron configuration for island. And what's especially interesting in the case of ions is that they're electron configuration is always YSL electronic with a noble gas that is having the same number of electrons as another atomic species. Electron affinity can be thought of as the opposite of the ionization energy, specifically, the energy change as a result of the addition of the electron. And generally the electron affinity increases across a period and decreases down a group. Metals have unique physical properties, including the fact that they are good conductors of heat and electricity and are malleable and ductile, and medals actually make up the majority of the periodic table. And conversely, non metals also have unique properties and can be thought of as the opposite of metals. So they tend to be poor conductors of heat and electricity and tend to be written and they make up a smaller present of the periodic table but are largely responsible for organic matter and life. As we know, metal Lloyds are the intermediate of metals and nonmetal, so they physically look like medals but actually have a behavior similar to that of non metals on day also have semiconducting properties that are unique and useful for tons of applications in the electronic industry. Alkaline earth metals and alkaline earth metals are types of metals with fans, electrons in the S orbital, which influences their behavior and reactions, and non metals, also composed of a variety of gasses, liquids and solids which have distinct properties and reactivity as well.
