Afixed amount of ideal gas is held in a rigid container that expands negligibly when heated. at 20°c the gas pressure is p. if we add enough heat to increase the temperature from 20°c to 40°c, the pressure will be:
a. equal to 2p
b. less than 2p
c. impossible to determine since we do not know the number of moles of gas in the container
d. greater than 2p
or
e. impossible to determine since we do not know the volume of gas in the container.

To practice problem-solving strategy 10.1 for energy conservation problems. a sled is being held at rest on a slope that makes an angle θ with the horizontal. after the sled is released, it slides a distance d1 down the slope and then covers the distance d2 along the horizontal terrain before stopping. find the coefficient of kinetic friction μk between the sled and the ground, assuming that it is constant throughout the trip.
