entropy of the system .If a compression or expansion of a gas takes place with no flow of heat energy either into or out of the gas - the process is said to be isentropic or adiabatic. The isentropic (adiabatic) process can be expressed with the Ideal Gas Law as: p / ρk = constant where k = cp / cv - the ratio of specific heats - the ratio of specific heat at constant pressure - cp - to the specific heat at constant volume - cv The isentropic or adiabatic process can also be expressed as

America experienced many hardships from the British‚ and at multiple times were let down from what they estimated they were deserving of. The “J curve” is known as a diagram indicating the climbing up and the sudden down of any idea‚ or action. The “J curve” is an accurate representation of the colonist’s expectations at the time of the “oppressive” British. The “J curve” seems to center around two main points for the colonists. The first was the wars they fought‚ the outcomes‚ and the government and

Topic Canada should subsidize renewable energy options such as wind and solar power in order to increase the share of renewables in Canada’s energy balance. Introduction Canada government subsidizes a number of socially beneficial services‚ including health care‚ education and energy services. Subsidies to the energy sector mainly are for oil and gas production‚ however‚ they are not all socially beneficial[figure 1]. In fact‚ they have negative impact for the environment and hinder

Molar Heat of Combustion Aim: To find the molar heat of combustion for four different alkanols: 1. Methanol 2. Ethanol 3. 1-Propanol 4. 1-Butanol - And to compare the experimental value with the theoretical. Background: The Molar Heat of Combustion of a substance is the heat liberated when 1 mole of the substance undergoes complete combustion with oxygen at standard atmospheric pressure‚ with the final products being carbon dioxide gas and liquid water.

has produced energy for billions of years. Solar energy is the sun’s rays (solar radiation) that reach the Earth. This energy can be converted into other forms of energy‚ such as heat and electricity. * In the 1830s‚ the British astronomer John Herschel famously used a solar thermal collector box (a device that absorbs sunlight to collect heat) to cook food during an expedition to Africa. Today‚ people use the sun’s energy for lots of things. solar energy can be used to: * Heat water — for

Romar M. Cabinta EXERCISES 15 WORK‚ ENERGY‚ AND POWER A. CONCEPTUAL QUESTIONS 1. Is work done when you move a book from the top of the desk to the floor? Why? Yes. It is because the displacement of the book from the top of the desk to the floor and the force that is applied to the book is parallel with one another. 2. State the law of Conservation of Mechanical Energy in two ways? The law of conservation of energy states that energy may neither be created nor destroyed.
