You find a geode while hiking. You place it on a scale and find it has a mass of 62 g.
You fill a graduated cylinder with water up to the 50 mL mark and place the geode
into the cylinder. The water rises to 81 mL. What is the density of the geode?
A. 1g/cm3

B. 4g/cm3

C. 2g/cm3

D. 3g/cm3

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.

8.98 dm3 of hydrogen gas is collected at 38.8 °c. find the volume the gas will occupy at -39.9 °c if the pressure remains constant.
