Evgesh-ka [11]

Answer:

The energy transferred between samples of matter because of a difference in their temperatures is called a. heat.

Explanation:

The first law of thermodynamics establishes that when two bodies with different temperatures are put in contact they will find thermic equilibrium to a final temperature by transferring heat. Thus the correct answer is (a).

Thermochemistry is the study of the transformations of heat energy on the chemical reactions. Chemical kinetics is the study of the rate of chemical reactions. And temperature is the measure of the heat.

If you purchase four 750 gram jars of table salt (NaCl) and dump them all onto 1,000 kg of snow, how much would the freezing poi
Minchanka [31]
Mass of NaCl = 750 g
mass of water = 1000 kg
Kf = - 1.86 °C 
moles of NaCl = \frac{mass (g)}{Molar mass}
                       = \frac{750 g}{58.5 g/mol} = 12.8 moles
molality of NaCl = \frac{moles of solute (NaCl)}{mass of solvent (kg)}
                        = \frac{12.82}{1000} = 0.01282 mole/kg
Δ Tf = Kf * m = -1.86 * 0.01282 = - 0.024 °C
