ENGINEERING THERMODYNAMICS FOR YEAR I ELECTRICAL 1 INTRODUCTION AND THE FIRST LAW OF THERMODYNAMICS All living things depend on energy for survival‚ and modern civilizations will continue to thrive only if existing sources of energy can be developed to meet the growing demands. Energy exists in many forms‚ from the energy locked in the atoms of matter itself to the intense radiant energy emitted by the sun. Many sources of energy exist: many are known‚ some perhaps unknown; but when

redistribution of energy. So the speed and energy of all the molecules of the gas at any instant are not the same. Thus‚ we can obtain only average value of speed of molecules. If there are n number of molecules in a sample and their individual speeds are u1‚ u2‚ …….un‚ then average speed of molecules uav can be calculated as follows: © no N C tt E o R be T re pu uav = u 1 + u 2 + .........un n Maxwell and Boltzmann have shown that actual distribution of molecular speeds depends on temperature and molecular

x2 ) if they have the same slope at that point. Now the slope of an indifference curve at (x1 ‚ x2 ) is the ratio −M U1 (x1 ‚ x2 )/M U2 (x1 ‚ x2 ). (This slope is also known as the marginal rate of substitution.) The slope of the budget line is −p1 /p2 . Therefore an indifference curve is tangent to the budget line at the point (x1 ‚ x2 ) when M U1 (x1 ‚ x2 )/M U2 (x1 ‚ x2 ) = p1 /p2 . This gives us one equation in the two unknowns‚ x1 and x2 . If we hope to solve for the x’s‚ we need another
