Answer:
<em>Heat</em>
Explanation: When matter is heated enough, the molecules move faster and with greater energy. If enough heat is added, a solid can become liquid and a liquid can become gas. In the same way, molecules slow down when they are cooled.
Moles=mass/mr(molar mass of CO2 found by adding mass numbers found on periodic table)
= 82/44
=1.86 moles (2d.p)
