Water in Space: What Happens?

Well, the temperature of space is, at its coldest, just the temperature of the leftover glow from the Big Bang. This radiation, known as the Cosmic Microwave Background, bathes the entire Universe in a temperature of only 2.7 Kelvin. That’s less than 3 degrees above absolute zero, or -455 degrees Fahrenheit! But there’s also — literally — no pressure in space. So, what happens? Who wins? Does the water freeze or boil?
