An object has a mass of 3.05 oz and a volume of 0.1032 l . what is the density (g/ml) of the object?

Predict whether the changes in enthalpy, entropy, and free energy will be positive or negative for the boiling of water, and explain your predictions. how does temperature affect the spontaneity of this process?

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.

What mass of natural gas (ch4) must you burn to emit 276 kj of heat?
