The heating curve of an unknown chemical

There are two parts to submit for this activity.

Part One: Using the data and observations in the table below, create a heating curve for hydrogen that Dr. Wong can reference during his laboratory testing.

Part Two: Create a model of the atoms of a substance moving through the solid, liquid, and gas states.

PART ONE:

Watch the video below on hydrogen gas storage before beginning your activity.

Understanding how atoms behave in different phases can help us to think about ways to create cleaner energy for things like this car I'm driving. Most cars run on gas, which releases carbon dioxide into the atmosphere, contributing to climate change. But what if we could run our cars on something that wasn't bad for the environment?

Peter Wong, of Tufts University, is thinking about how we can power our vehicles with hydrogen instead of fossil fuels. Hydrogen is used in fuel cells, devices that use hydrogen and oxygen to create electricity.

[Animation of a hydrogen fuel cell that shows three plates, blue with a positive, white, and red with a negative. The H two is going into the blue on the left and the O two is going into the red on the right. An arrow points left from the center white cell into the blue cell labeled O H minus. There is a connection between the negative and positive terminals labeled energy out and water H two O escapes from the top of the cell.]

So what's really nice about fuel cells is that it uses hydrogen, oxygen from the air, and creates electricity, and the only byproduct is water, which isn't harmful to our environment.
