Hi, I'm Zola with another NASA fact.

2
00:00:06,000 --> 00:00:09,000
Why is NASA boiling fluids in space?

3
00:00:09,000 --> 00:00:12,000
Boiling fluids in space is simpler than boiling fluids on Earth.

4
00:00:12,000 --> 00:00:15,000
Experiments in space help us understand boiling.

5
00:00:15,000 --> 00:00:17,000
How do things boil in space?

6
00:00:17,000 --> 00:00:19,000
Let's check it out.

7
00:00:19,000 --> 00:00:23,000
In space, the vapor created by heating forms one giant bubble.

8
00:00:23,000 --> 00:00:26,000
On Earth, the vapor forms thousands of tiny bubbles.

9
00:00:26,000 --> 00:00:27,000
How come?

10
00:00:27,000 --> 00:00:31,000
Convection, or the rising of warmer fluids,

11
00:00:31,000 --> 00:00:34,000
and buoyancy, or floating of less dense fluids,

12
00:00:34,000 --> 00:00:37,000
don't exist in the weightless environment of space.

13
00:00:37,000 --> 00:00:40,000
Why is it useful to understand boiling?

14
00:00:40,000 --> 00:00:43,000
If we understand boiling better, we can improve many technologies.

15
00:00:43,000 --> 00:00:48,000
Power plants on Earth and the cooling of spacecraft both use boiling to transfer energy.

16
00:00:48,000 --> 00:00:51,000

Until next time, I'm Zola with another cool NASA fact.
