Why does wood feel warmer than metal when they are really at the
same temperature (room temperature)?
2.
Sometimes linear expansion is the important thing, as in being
sure that a structural beam has room to expand into if it gets
hot, and sometimes volume expansion is the important thing,
as in a mercury thermometer. Say why, for a given substance,
the coefficient of volume expansion is three times the coefficient
of linear expansion.
3.
The pressure on an ideal gas is doubled while its temperature
is kept the same. What happens to its volume?
