To do this computation for each of the four metals, you needed several measurements.

▪ First, you measured the (_answer_) of the metal and the water inside the calorimeter.
▪ Then, you (_answer_) the metal and added it to water in the calorimeter.
▪ After heat transferred from the metal to the water, you measured the (_answer_) of both materials.

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.

Gasoline has a density of 0.740 g/ml. if you have 328 grams of gasoline, what is the volume in milliliters?

Calculate the standard enthalpy of formation of liquid methanol, ch3oh(l), using the following information: c(graphite) + o2 latex: \longrightarrow ⟶ co2(g) latex: \delta δ h° = –393.5 kj/mol h2(g) + o2 latex: \longrightarrow ⟶ h2o(l) latex: \delta δ h° = –285.8 kj/mol ch3oh(l) + o2(g) latex: \longrightarrow ⟶ co2(g) + 2h2o(l) latex: \delta δ h° = –726.4 kj/mol
