The temperature of 3.00 mol of an ideal diatomic gas is increased by 40 degrees C without a change in pressure. The molecules in the gas rotate but do not oscillate.
(a) How much energy is transferred to the gas as heat?
(b) What is the change in the internal energy of the gas?
(c) By how much does the rotational kinetic energy of the gas increase?
A small button placed on a horizontal rotating platform with diameter 0.328 will revolve with the platform when it is brought up to a rotational speed of 45.0 rev/min , provided the button is a distance no more than 0.141m from the axis. a)What is..
