In a constant-volume process, 202 J of energy is transferred by heat to 0.90 mol of an ideal monatomic gas initially at 297 K. (a) Find the work done on the gas. (b) Find the increase in internal energy of the gas. (c) Find its final temperature.

A wire 100 meter long at 20 °C has a linear temperature coefficient of 2 * 10-51. The wire is heated and expands to a length of 100.01 m. What is the final temperature?

An atomizer forms water droplets 45μm in diameter. Determine the excess pressure within these droplets using σ = 0.0712 N/m.

Determine the magnitudes of F1, F2 and F3 for equilibrium of the particle. (Figure 1)

3.5 kg of an ideal gas is heated at constant temperature from 15 m3 and 4.0 atm to 35 m3 at Determine the work done

For the open tank, the piezometers attached on the side, containing two different immiscible liquids, as shown in the figure, find the elevation of the liquid surface in piezometer A.

To ensure a tight fit, the aluminum rivet used in airplane construction are made slightly larger than the rivet holes and cooled by dry ice (solid CO2) before being driven. If the diameter of a hole is 0.500 cm, what should be the diameter of a rive at 20 degree Celsius if its diameter is equal that of a hole when the rivet is cooled to -78 degree Celsius, the temperature of dry ice? Assume the coefficient of expansion to remain constant.

A poorly designed electronic device has two bolts attached to different parts of the device that almost touch each other in its interior as in the figure. The steel and brass bolts are at different electric potentials, and if they touch, a short circuit will develop, damaging the device. The initial gap between the ends of the bolts is d = 5.0 mm at 27°C. At what temperature will the bolts touch? Assume the distance between the walls of the device is not affected by the temperature change. Steel 0000000 0.010 m 0.030 m Brass 5.0 μm
