Which statement best describes the direction of heat flow by conduction between two samples of the same material?
heat flows from faster molecules to slower molecules when they are near.
heat flows from faster molecules to slower molecules when they collide.
heat flows from slower molecules to faster molecules when they are near.
heat flows from slower molecules to faster molecules when they collide.
i was once told it was not c but that didnt me.

Precision can be defined as the o exact center of a data set. o reproducibility of a measured value. o correlation between two variables that are measured in a data set agreement between a measured value and an accepted value.

Which suspect most likely committed the robbery and how do you know

There are two steps in the usual industrial preparation of acrylic acid, the immediate precursor of several useful plastics. in the first step, calcium carbide and water react to form acetylene and calcium hydroxide: cac2 (s) + 2h2o (g) → c2h2 (g) + caoh2 (s) =δh−414.kj in the second step, acetylene, carbon dioxide and water react to form acrylic acid: 6c2h2 (g) + 3co2 (g) + 4h2o (g) → 5ch2chco2h (g) =δh132.kj calculate the net change in enthalpy for the formation of one mole of acrylic acid from calcium carbide, water and carbon dioxide from these reactions. round your answer to the nearest kj .
