=== USER  (2026-09-11T04:44:19Z) ===
I’m cooking at 2,000 m altitude. Does water boil hotter or cooler than at sea level, roughly what temperature, and does that make my pasta cook faster or slower?

=== [1] THINKING ===
The user is asking about boiling point at 2000m altitude. This is a physics question — the boiling point drops with altitude because atmospheric pressure is lower. Let me verify the numbers with a tool rather than relying on memory.

At sea level, water boils at 100°C (1 atm = 101.3 kPa).
At 2000m, atmospheric pressure is roughly 80 kPa (about 80% of sea level).

The boiling point at 80 kPa is roughly 93°C. Let me verify this.

Actually, the standard approximation: pressure drops about 12% per 1000m, so at 2000m it's about 80% of sea level. The boiling point drops roughly 1°C per 285m of altitude, so at 2000m that's about 7°C lower, giving ~93°C.

Let me check this with a tool to be sure.

=== [10] THINKING (4s) ===
The table shows boiling point vs altitude. At 2000 m (which is 6562 ft), the boiling point is about 93.1°C (from the 6500 ft / 1981 m row showing 93.1°C). Let me look more carefully:

- 6250 ft (1905 m): 93.4°C
- 6500 ft (1981 m): 93.1°C
- 6750 ft (2057 m): 92.9°C

So at exactly 2000 m, it's approximately 93°C.

Now for the pasta question: since the water is cooler (93°C vs 100°C), the pasta cooks slower. The starch gelatinization and protein denaturation processes are temperature-dependent, so lower temperature means slower cooking. This is well-established cooking science.

Let me give a clear, complete answer.

=== [11] ASSISTANT TEXT ===
Here's what's happening at 2,000 m:

**Boiling point: roughly 93 °C (199 °F)**

At sea level water boils at 100 °C because the atmospheric pressure is about 101 kPa. At 2,000 m the pressure drops to roughly 80 kPa, so water reaches its boiling point about 7 °C earlier. (The Engineering ToolBox table gives 93.1 °C at 1,981 m and 92.9 °C at 2,057 m, so 93 °C is a solid figure for 2,000 m.)

**Pasta: it cooks slower, not faster**

This is the part that trips people up — the water is *still* boiling, so it feels like it should be just as hot, but it isn't. Starch gelatinisation and the protein network that makes pasta "al dente" are both temperature-dependent. At 93 °C those reactions proceed more slowly than they would at 100 °C, so:

- Expect to add roughly **20–30 % more cooking time** than the package says.
- The pasta will also absorb a bit more water as it sits in the cooler bath longer, so don't over-soak it.
- You can't make up the difference by turning the heat up — once it's at a rolling boil the temperature is capped at 93 °C no matter how hard the burner works.

**Practical tips for high-altitude pasta:**
- Use a little more water so the temperature stays stable when you drop the pasta in.
- Salt the water generously (it still helps flavour and raises the boiling point by a fraction of a degree).
- Taste a minute or two before the adjusted time — "al dente" at 93 °C feels slightly different from al dente at 100 °C.
