Question

Which statement best describes the shape and volume of an aluminum cylinder at STP?
(1) It has a definite shape and a definite volume.
(2) It has a definite shape and no definite volume.
(3) It has no definite shape and a definite volume.
(4) It has no definite shape and no definite volume.

Answer 1

The answer to this question would be : (1) It has a definite shape and a definite volume.

STP stands for Standard Temperature and Pressure which was about 273K temperature and 1 atmosphere pressure. In standard temperature and pressure, aluminum would be solid and its volume should be measurable.
