Temperature, the average kinetic energy of particles, tells you how warm something is. Thermal energy, the total kinetic energy of the particles, tells you the extent to which a substance or object can transfer heat or make something else warmer. If an object's temperature increases, its thermal energy increases also.

Answer from: cjkc

temperature a measurement of the average amount of energy PER UNIT OF STUFF

Heat Energy is TOTAL ENERGY IN THE STUFF

So, that's why the difference. If you have two things at the same temperature, then any one mole (which is the same as how many molecules or atoms it takes to make up the molecular weight of something in grams.. so one mole of Hydrogen weighs 1 gram, 1 mole of helium weighs 2 grams, 1 mole of Gold weight 196 grams) of the stuff will have the same amount of energy as one mole of the other stuff. If you measure by total mass though, then you realize that there are more water molecules than gold ones in the same volume of stuff, and heat is about volume and molecular density, not mass.

This is why some Stirling engine folks who have made solar plants use Helium as the working gas.. it contains a huge amount of heat for its volume (also because it is very compressible)

So.. Delta Q goes with moles, not mass.

Answer from: Quest

a). in this case, dh> 0 and sd> 0. if t becomes larger, the term "-tds" will become more negative. at some point, it is possible that -dts will be more negative than the dh is positive, and the reaction will become spontaneous. this is probably the correct answer, but you should look at all of the other possibilities and make sure of that.

Mg-26 and mg-24 are pair of isotopes. isotopes are defined as atoms of the same element having same atomic number but different mass number. i hope that was .

100 grams of molten lead (600°c) is used to make musket balls. if the lead shot is allowed to cool to room temperature (21°c), what is the change in entropy (in j/k) of the lead? (for the specific heat of molten and solid lead use 1.29 j/g⋅°c; the latent heat of fusion and the melting point of lead are 2.45 × 104 j/kg and 327°c, respectively.)
