Why does the hood of a car heat up after the car has been running for a while? a) according to the fourth law of thermodynamics, the temperature of the other parts of the car increases due to the coolant used for the engine. b) according to the first law of thermodynamics, the hood of the car heats up using heat from the surroundings in-order to achieve thermal equilibrium with the engine. c) according to the second law of thermodynamics, not all energy from the burnt fuel is used to do work on the piston. it also produces heat which warms other parts of the car. d) according to the third law of thermodynamics, the increase in the velocity of the car changes the entropy of the tires. to balance this change, the temperature of the other parts is increased.

Calculate the ratio of h+ ions to oh– ions at a ph = 6. find the concentration of h+ ions to oh– ions listed in table b of your student guide. then divide the h+ concentration by the oh– concentration. record this calculated ratio in table a of your student guide. compare your approximated and calculated ratios of h+ ions to oh– ions at a ph = 6. are they the same? why or why not? record your explanation in table a. what is the concentration of h+ ions at a ph = 6? mol/l what is the concentration of oh– ions at a ph = 6? mol/l what is the ratio of h+ ions to oh– ions at a ph = 6? : 1
