sublimes completely at 178 deg. C.
judge verdicts (2)
- groundedness 1.00 pass — The claim is directly stated in the passage: 'It melts at 235-7 deg. C. and sublimes completely at 178 deg. C.' The exact wording from the passage matches the claim with only minor notation changes (deg. C. to degrees Celsius).
- qualifier_fidelity 1.00 pass — All qualifiers are faithful to the passage. The viewpoint is correctly attributed to the author (the passage presents this as factual information from a scientific text). The stance is appropriately 'asserts' as the passage states this as a definitive property. The sentiment is neutral, matching the passage's objective scientific tone. The time qualifiers are correctly set to null since the passage provides no temporal context. The context is empty, which is appropriate as the passage does not restrict this property to a particular sense or role. The quote 'sublimes completely at 178 deg. C.' appears verbatim in the passage and directly supports the claim.
