Question 1

Which of the following substances has the greatest specific heat?

copper

ice

water

steam

Ice, water, and steam have equal specific heats since they are the same material, and this specific heat is greater than that of copper.


Question 2

Which statement below regarding the First Law of Thermodynamics is most correct?

A system can do work externally only if its internal energy decreases.

The internal energy of a system that interacts with its environment must change.

No matter what other interactions take place, the internal energy must change if a system undergoes a heat transfer.

The only changes that can occur in the internal energy of a system are those produced by non-mechanical forces.

The internal energy of a system cannot change if the heat transferred to the system is equal to the work done by the system.

People who have myopia, or nearsightedness, are not able to see objects at a distance but only up close. It occurs when the cornea is either curved too steeply, the eye is too long, or both. This condition is progressive and worsens with time. More than 100 million people in the United States are nearsighted, but only 20% of those are born with the condition. Diet, eye exercise, drug therapy, and corrective lenses can all help manage nearsightedness.
