15. Show that 60.0 L of gasoline originally at 15.0°C will expand to 61.1 L when it warms to 35.0°C, as claimed in Example 13.4
Calculate the final volume of 50 L of gasoline originally at 14 degrees Celsius when it warms to 36 degrees Celsius.
A car has a 50 L steel gas tank filled to the top with gasoline when the temperature is 10°C. The coefficient of volume expansion of gasoline is β = 0.900 ✕ 10-3 K-1. Taking the expansion of the steel tank into account, how much gasoline spills out of the tank when the car is parked in the sun and its temperature rises to 28°C? Answer: ____ L

A sample of gas originally occupies 25.94 L at 0.00°C. What is its new volume when it is heated to 21.00°C? (Assume constant pressure.)
A sample of gas originally occupies 27.48 L at 0.00°C. What is its new volume when it is heated to 23.00°C? (Assume constant pressure.)
An idealized diesel engine operates in a cycle known as the air-standard diesel cycle shown in the figure below. Fuel is sprayed into the cylinder at the point of maximum compression, B. Combustion occurs during the expansion B-C, which is modeled as an isobaric process. Show that the efficiency of an engine operating in this idealized diesel cycle is given by the following expression.

5. 20% A 2.4-L gasoline fuelled internal combustion engine produces a maximum power of 220 kW when the fuel is burned stoichiometrically with air. The thermal efficiency of the engine at this maximum power is 43%. Methanol (CH3OH) is to be used as an alternative biofuel for this engine. The stoichiometric air-fuel ratio for gasoline is 14.6. Assume a combustion efficiency of 98%. The lower heating values of gasoline and methanol are 44 MJ/kg and 20 MJ/kg, respectively. Consider the...
The electric field along the axis of a uniformly charged disk of radius R and total charge Q is given below. Ex = 2πkeσ 1 − x (x2 + R2)1/2 Show that the electric field at distances x that are large compared with R approaches that of a particle with charge Q = σπR2. Suggestion: First show that x (x2 + R2)1/2 = 1 + R2 x2 −1/2 , and use the binomial expansion (1 + δ)n ≈ 1 +...
