A 1.00 m 3 container of air absorbs 5857 J of heat at a constant pressure of 1.00 atm. Air has a density of 1.20 kg/m 3, a constant-pressure specific heat of 10*10 J/(kg·°C), and a thermal coefficient of expansion of 3.67 X10-3 (°C)-1.
1. Find the work done by the air.
2. Find the increase in the air's internal energy.
3. Find the increase in the temperature of the air.
When water freezes, it expands about 8.95%. What would be the pressure increase inside your automobile's engine block if the water in it froze
Through a rockslide, a 770 kg rock slides from rest down a hillside that is 500 m long and 300 m high. The coefficient of kinetic friction among the rock and the hill surface is 0.29. How much energy is transferred to thermal energy through the slide
Consider a very long solid insulating cylinder with radius a and with positive net charge 2Q inside a conductor cylinder same length with inner radius b and external radius c with the same central axes and a net charge -Q(radius a
A billiard ball A moving at 5.00m/s hits another ball B, initially at rest, of the same mass. Find the velocity (magnitude and direction) of the second ball after the collision
A 500-turn solenoid is 23 cm long, 1.5 cm in diameter, and carries 65 mA. How much magnetic energy does it contain
The length of a beam increases by 1.26mm when its temperature is raised from 29.87oC to 71.49 oC. What is the length of the beam at the initial temperature
A cube of metal has a mass of 0.569 kg and measures 3.09 cm on a side. Calculate the density and identify the metal
A 1.63 kg block of ice is sliding by you on a very slippery floor at m/s. As it goes by, you give it a kick perpendicular to its path. Your foot is in contact with ice block for 0.005 seconds. The block eventually slides at the angle of 24 degre..
What is the mean free path for the molecules in an ideal gas when the pressure is 100 kPa and the temperature is 300 K given that the collision cross-section for the molecules of that gas is 2.0 × 10-20 m2? Boltzmann's constant is k = 1.38 × 10-23..
