Question

The molar heat capacity of crystalline a D- glucose, plotted is (c_p/T) against T is shown. The area finder the curve from 0 to 298 k yields which thermodynamic. Absolute entropy at 298 k enthalpy of formation at 298 k entropy of formation at 298k gibbs energy at 298 k the temperature of the cooling liquid for an ideal engine is 7 deg C what must be the upper operating temperature if the efficiency is to be 30% 127k 196k 400k 520k the correct expression for calculating Delta s when an ideal gas is heated from T_2 to T-1 at constant pressure is Delta s= integral _t_2 _T_1 C_v/T dT, Delta s + Delta R ln(V_2/V_1) Delta _s = Delta H/T-st Deltas= integral T_2 _T_1 C_v/T dT when one mole of ideal gas is heated under the from 300k to 500k what is the volume of the given entropy Deltas? 0 (3/2) R ln(5/3) what was the signal Delta S for the system significance when the following of liquid water at 5 deg C the general expression for the isothermal of material is x_T= -1/v(partial v/partial P)_t for most solids and liquids C_t. increases an temperature increased because higher temperature yield. Larger average intermolecular distances making compression easier. Smaller average intermolecular distances making compression easier. Smaller average intermolecular distances making compression more difficult larger average intermolecular distances making compression more difficult. Which process has Delta s less than 0? Melting of gallium dissolution of salt in water decomposition of hydrogen peroxide formation of Al_2O_2 from its elements which must be true for a chemical reaction as the temperature approaches 0k? Delta H approaches Zero Delta G approaches Zero Delta G approaches Delta H Delat, 5 approaches unity one Maxwell relation is (partial p/partial T) =(partial S/partial V)_v why is this useful? The variation of s with v at constant T can thus be determined from easily measured quantities. The change in v can be measured from absolute enterprise at constant T. The internal energy does not change at constant T and V it is easier to hold V constant than to hold T constant The Helmboltz energy, A, is particularly useful quantity for processes under constant T and P T and V S and P S and V

Cooling is also needed because high temperatures damage engine materials and lubricants. Cooling becomes more important in when the climate becomes very hot.[1] Internal-combustion engines burn fuel hotter than the melting temperature of engine materials, and hot enough to set fire to lubricants. Engine cooling removes energy fast enough to keep temperatures low so the engine can survive.
