Physics Conceptual Final Exam Questions
And Answers Latest Update
Rod A has twice the diameter of rod B, but both are made of iron
and have the same initial length. Both rods are now subjected to
the same change in temperature (but remain solid). How would the
change in the rod's lengths compare? -
correct answer ✅Rod A= Rod B
In thermal expansion the change in length is independent of the
rod's diameter or cross-sectional area
The linear expansion of a material depends on which of the
following? -
correct answer ✅The type of material, the length of the material,
and the change in temperature of the material
A steel plate has a hole in it with a diameter of exactly 1.0cm when
the plate is at a temperature of 20 C. A steel ring has an inner
diameter of exactly 1.0 cm at 20 C. Both the plate and the ring are
heated to 100 C. Which statement is true? -
correct answer ✅The hole in the plate and the opening in the ring
get larger.
On mole of an ideal gas in a sealed rigid contained is initially at a
temperature of 100 C. The temperature is then increased to 200 C.

The pressure in the gas -
correct answer ✅Increases by about 25%
The temperature of an ideal gas increases. Which of the following is
true? -
correct answer ✅The pressure, the volume, or both, may increase
An ideal gas is in a sealed rigid container. The average kinetic energy
of the gas molecules depends most on -
correct answer ✅the temperature of the gas.
The temperature of the gas is a measure of the average kinetic
energy of the gas molecules.
In a mixture of the gases oxygen and helium, which statement is
valid? -
correct answer ✅The helium atoms will be moving faster than the
oxygen molecules, on average
When using the ideal gas law, which of the following rules must be
obeyed? -
correct answer ✅Always use temperature in kelvins and absolute
pressure
