In the sun, hydrogen is converted to through nuclear fusion.

helium
carbon
water

Melting and boiling are endothermic processes. this means that these processes absorb energy from their surroundings in order to occur. use this information and the data you collected in the phase change gizmo to describe what happens to the temperature of water when you boil it, then explain why this result occurs.

Suppose you wanted to make 100 grams of water. what is the molar mass of water (h2o)?

Find the mass, in grams, of 5.00*10^23 molecules of f2
