a
Its mass has no change, and its weight increases.
b
Its mass decreases, and its weight has no change.
c
Its mass has no change, and its weight decreases.
d

Question 18
Temperature and kinetic energy are _____________ related, so when one increases, the other increases too.

a
somehow
b
inversely
c
directly
d
oppositely

Answer 1

1) a — Its mass has no change, and its weight increases. (Mass is intrinsic; gravity on Earth is stronger so weight increases.)

2) c — directly. (Higher temperature means greater average kinetic energy of particles.)
