How long after the iceberg hit did the first lifeboat leave?
at 12:45 a.m.
It's a VERY long ending to the Titanic. 1. The ship hit an Iceberg on her Maiden Voyage: April 14, 1912 11:40 P.M. 2. The people was unaware about the danger intill 12:45 A.M., when the first lifeboat left. 3. The Captain didn't survived. 4: The Titanic's #1 funnel fell at 2:00 A.M. 5: The Titanic broke apart and sunked
The exact size of the iceberg will probably never be known, but according to early newspaper reports the height and length of the iceberg was approximated at 50 to 100 feet high and 200 to 400 feet long. However, these dimensions only relate to the estimated size above water. Around 85% of an iceberg is below water. Therefore multiplying the estimates you have an iceberg with a volume of between 810,00 and 3,240,000 square feet…
Its a rather broad question of thermodynamics. To determine this you would have to determine the specific heat of iceburg to meet the desired criteria (33 degrees). As well as the amount of joules of energy applied to the iceberg and the ambient temperature surrounding the iceberg. I hope this answer was as broad as the question.
