When cold milk is added to hot tea, the liquids slowly blend together as the cooler liquid mixes with the warmer liquid. Eventually, the heat will be distributed evenly through the entire liquid. Which best explains the reason the heat spreads through the liquid?

Measuring which physical property is most likely to produce the most precise results when trying to identify a substance

Apiece of copper has a temperature of 75.6 0c. when the metal is placed in 100.0 grams of water at 19.1 0c, the temperature rises by 5.5 0c. what is the mass of the metal?

Ican determine the molar mass of an element by looking on the under the atomic mass for the element. for example the molar mass of phosphorus is 30.974 grams/mole. avogadro’s number tells me the amount of representative particles in 1 mole of any substance. this means 12.011 gram sample of carbon and a 32.0 gram sample of sulfur have the same number of atoms.
