Thermal expansion is the tendency of matter to change in volume in response to a change intemperature.[1] All materials have this tendency. When a substance is heated‚ its particles begin moving more and thus usually maintain a greater average separation. Materials which contract with increasing temperature are rare; this effect is limited in size‚ and only occurs within limited temperature ranges. The degree of expansion divided by the change in temperature is called the material’s coefficient

Kinetic Theory Objectives • Describe how the kinetic-molecular theory is used to explain how gases behave at different temperatures. (Exploration 1) • Analyze data that shows how gas particle mass affects that gas’s behavior. (Exploration 2) • Describe the Maxwell-Boltzmann Distribution. (Explorations 1 and 2) Description of Activity The kinetic-molecular theory states that a collection of gas molecules’ average kinetic energy has a specific value at any given temperature

The government I call this form of Government‚ a constitutional Oligarchy. In the Constitution of this nation‚ it is stated that there are three branches to this country‚ similar to our country. The first branch is the Oligarchy (ruled by few). There are three consuls‚ basically dictators that have been elected from the “Higher Council” (which will be talked about later). The Consuls rule every aspect of Government; the economy‚ trade‚ commerce‚ etc. however‚ even with all the power they hold‚

“What are the greatest lessons learned by Filipinos from their colonial experiences? Explain?” Being brave‚ well-disciplined‚ helpful and also love for their country are some of the lessons they had learned. They fight for their own freedom. They not allow their selves to be under controlled by other races. They learned to love their country because if they will allow it to be conquered‚ they will lose their own home. They will be slaves forever. Filipinos learned to be strong‚ not to give up
