00:00:05.330 --> 00:00:12.300
And now it's time for gassy games. Here's your host, Alice. Hello, and welcome back to

00:00:12.300 --> 00:00:17.160
Gassy Games. I'm Alice, your host. Today we have a full day of science questions.

00:00:17.160 --> 00:00:20.440
If you're joining us here for the first
time, here's how to win.

00:00:20.440 --> 00:00:24.740
Each correct answer earns you two points and each incorrect answer deducts one point from

00:00:24.740 --> 00:00:27.720
your total score. The last question is
worth three points.

00:00:28.020 --> 00:00:33.080
Today's prize is a free, two-hour-long hot air balloon ride.  First question. Are the contestants ready?

00:00:33.280 --> 00:00:34.940
Yeah.

00:00:34.940 --> 00:00:36.780
Does gas have mass?

00:00:36.900 --> 00:00:37.520
[buzzer ringing]

00:00:37.520 --> 00:00:40.020
Gas has no mass since you can't feel it or touch it.

00:00:40.020 --> 00:00:45.390
How would you measure its mass? Incorrect, not only does gas have mass, but

00:00:45.390 --> 00:00:48.989
it can take you to high places. Sorry
Michael but that answer doesn't get you

00:00:48.989 --> 00:00:53.640
any closer to winning today's hot air
balloon prize.  You can't even tell gas is there.

00:00:53.980 --> 00:01:00.520
How would it have mass?  Wait, what exactly is mass?

00:01:01.500 --> 00:01:02.480
[buzzer ringing]

00:01:02.480 --> 00:01:05.460
Mass is a quantity representing the amount of matter in an object.

00:01:05.640 --> 00:01:06.720
Correct.

00:01:06.720 --> 00:01:08.660
John earns two points.

00:01:08.700 --> 00:01:13.760
Wait, whoa.
What's the matter? That brings us to our next question.

00:01:13.960 --> 00:01:15.480
Does anyone know what
matter is?

00:01:15.480 --> 00:01:16.220
[buzzer ringing]

00:01:16.220 --> 00:01:18.300
Matter is anything that has mass.

00:01:18.420 --> 00:01:22.040
Solids, liquids and gases are all
states of matter and they all have mass.

00:01:22.200 --> 00:01:28.460
Right two points for Jira. Since gas is
matter, it has mass. Do you get it now?

00:01:29.140 --> 00:01:35.100
Not really.  Alright, here's an example.
Two balloons with the same mass are on a scale,

00:01:35.380 --> 00:01:40.900
but when you put air in one of
them, the balloon with more gas has more mass.

00:01:41.320 --> 00:01:44.700
So does everyone understand now
that gas has mass?

00:01:46.060 --> 00:01:50.640
Here is the bonus question of the day.   Remember it's worth a total of three points.

00:01:50.800 --> 00:01:53.260
Give me an explanation of why gas has mass.

00:01:53.260 --> 00:01:54.280
[buzzer ringing]

00:01:54.320 --> 00:02:00.440
Gas is one of the states of matter so it has mass because matter has mass.

00:02:00.640 --> 00:02:02.440
Great, three points for Michael!

00:02:02.500 --> 00:02:08.200
And now it's time to announce today's final scores. John, Jira, and Michael have all tied at two points.

00:02:08.200 --> 00:02:10.520
Everyone has won the first-place prize.

00:02:10.740 --> 00:02:14.940
This has never happened before, but they all get a free, two-hour-long hot air balloon ride.

00:02:15.120 --> 00:02:18.800
That's all the time we have for today.
Thank you for tuning in to Gassy Games.

00:02:19.720 --> 00:02:22.560
Bye.
