Check your ‘facts’.
The persians didn’t have freezers, they had icehouses. They were able to collect and store ice during the winter, and use underground insulated ‘ice houses’ to keep it frozen over the summer. They didn’t actually produce ice in summer, they just got out what they had saved from the winter.
Check your uppity attitude, as we all knew what they meant by “freezer”.
They specifically said it could “create ice” not that it could keep ice. To create ice you need to remove energy from the system or you would just be melting ice to make less ice. There is a difference and most people will confuse it if they don’t know better.
Who’s the one with the attitude? He was right too.
If you can maintain ice to be solid all year long then wouldn’t internal temperature of the “ice house” be 32 degrees (F) or lower on average to keep it from melting? which means water would still freeze and yes create ice. other wise if it was above 32 the ice would melt over the entire year.
i thought hours and minutes and seconds were divisions of the day, why isn’t it exactly 24 hours?
Because the earth is also going around the sun, this adds about 4 minutes on to every day.
It takes a lot of energy to phase change ice into water. You end up with a mix of ice at 0 degrees C (32F) and water at 0 degrees C. That’s how, with a good sized mass of well insulated ice, you can keep it over a summer. You can’t change 0 degree water back into ice with out some way to remove the exess energy eg a freezer.
