Final answer:
The temperance movement was indeed influenced by urbanization and immigration, which is true. Not all tribes in the Iroquois Confederacy were neutral during the Revolutionary War; this statement is false. The ice cube and thread experiment relates to freezing point depression and is true.
Step-by-step explanation:
The temperance movement arose during a period of significant social changes, including increased urbanization and immigration. This is true. As cities grew and immigrant populations increased, alcohol consumption was seen as a societal issue, leading to efforts to curb drinking through organized campaigns, of which the temperance movement was a part.
Regarding the Iroquois Confederacy during the Revolutionary War, it is false to assert that all tribes maintained neutrality. The Confederacy was actually split, with some tribes siding with the American colonists and others with the British.
When it comes to the phase change and latent heat, the concept of a salted ice cube allowing a thread to stick and lift the cube is true. This is an example of freezing point depression caused by the salt, which melts the ice and then re-freezes, encasing the thread.
