A soup-cooling table gives temperatures at \(0,~10,~20,~30,~\text{and}~40~\text{minutes}\) as \(180^{\circ}\text{F},~170^{\circ}\text{F},~163^{\circ}\text{F},~159^{\circ}\text{F},~\text{and}~158^{\circ}\text{F}\). Test every statement below against the table and report the complete set of supported statement numbers.

1. The soup is \(163^{\circ}\text{F}\) after \(20~\text{minutes}\).
2. The temperature drops by \(10^{\circ}\text{F}\) every \(10~\text{minutes}\).
3. The soup cools by a smaller amount from \(30~\text{to}~40~\text{minutes}\) than from \(0~\text{to}~10~\text{minutes}\).
4. At \(40~\text{minutes}\), the temperature is \(\text{below}~160^{\circ}\text{F}\).
5. The soup heats up over time.
