The photograph shows rockets carrying a space shuttle off the launchpad. The main source of fuel for this shuttle is liquid nitrogen and liquid hydrogen. Both are mixed and are burned together to power the main rocket engines. When the fuel ignites to create an upward motion for the shuttle, choose the correct statement that best describe the changes occurring.

As the fuel burns, energy is released to create an upward motion of the shuttle. This is an example of physical change because the color of the fuel changed.

As the fuel burns, energy is released to create an upward motion of the shuttle. This is an example of physical change because the size of the fuel particle changed.

As the fuel burns, energy is released to create an upward motion of the shuttle. This is an example of chemical change because two chemicals react to ignition, which in return changes their composition to a new substance.

As the fuel burns, energy is released to create an upward motion of the shuttle. This is an example of chemical change because the liquid nitrogen changes to gas.
