Which of these best describes the relationship between density and the rate of heat transfer? A.) Heat transfers between objects regardless of density.
B.) The greater the difference in densities between objects, the slower the heat will transfer.
C.) The less dense the object, the faster the heat will transfer.
D.) The denser the object the faster the heat will transfer.

What is the approximate vapor pressure when the gas condenses at 70 degrees celsius

Match each statement with the state of matter it describes

In a laboratory determination of the atomic weight of tin, a sample of tin is weighed in a crucible. nitric acid is added, and the reaction proceeds to give a hydrated tin(iv)oxide plus no2and h2o. the hydrated tin(iv)oxide is then heated strongly and reacts as follows: sno2.xh2o(s)sno2(s)+ xh2o(g)the sno2is finally cooled and weighed in the crucible. explain the effect on the calculated atomic weight of tin that would result from each of the following experimental errors: (a)considerable spattering occurs when the nitric acid is added to the tin.(b)the hydrated tin(iv)oxide is not heated sufficiently to change it completely to tin oxide.
