Chapter 1, Problem 60P(choose chapter or problem)
Answer the following true or false. Explain.
(a) \(1 \mathrm{~N}\) equals \(1 \mathrm{~kg} \cdot \mathrm{m} / \mathrm{s}^2\) but \(1 \mathrm{lbf}\) does not equal \(1 \mathrm{lb} \cdot \mathrm{ft} / \mathrm{s}^2\).
(b) Specific volume, the volume per unit of mass, is an intensive property while volume and mass are extensive properties.
(c) The kilogram for mass and the meter for length are examples of SI base units defined relative to fabricated objects.
(d) If the value of any property of a system changes with time, that system cannot be at steady state.
(e) The composition of a closed system cannot change.
(f) According to Archimedes’ principle, the magnitude of the buoyant force acting on a submerged body is equal to the weight of the body.

ANSWER:Solution 60P:
Here we need to state whether these statements are true or false with explanation.
(a) 1 N equals 1 kg · m/s2 but 1 lbf does not equal 1 lb · ft/s2.
This is true.
Because we know the conversation oflbf, which is equal to
.
(b) Specific volume, the volume per unit of mass, is an intensive property while volume and mass are extensive properties.
This is false.
