Weight depends on gravitational field strength

Steps:

• Recall that weight is the force due to gravity, calculated as mass times gravitational field strength (W = m × g).
• Identify that mass remains constant regardless of location.
• Note that gravitational field strength (g) increases slightly in the new location.
• Conclude that weight increases because g is larger while mass is unchanged.

Why C is correct:

• Weight is defined as W = m × g; an increase in g directly increases weight for the same mass.

Why the others are wrong:

• A: Density is mass divided by volume; neither mass nor volume changes with gravity.
• B: Mass is an intrinsic property and does not vary with location or gravitational field.
• D: Volume is determined by the object's material and temperature, not gravitational field strength.

Final answer: C
