Answer:
C. Thermal energy
Explanation:
Thermal energy is the sum of the kinetic and potential energy of all the particles in an object.
Answer:
31.2K
Explanation:
The following data were obtained from the question:
n = 1.42 mol
V = 3L
P = 123 kPa = 123000Pa
Recall: 101325Pa = 1atm
123000Pa = 123000/101325 = 1.21atm
R = 0.082atm.L/Kmol
T =?
Using the ideal gas equation PV = nRT, we can obtain the temperature as follows:
PV = nRT
T = PV/nR
T = (1.21 x 3)/(1.42 x 0.082)
T = 31.2K

Answer:
wax, candlewick, and oxygen
Explanation:
The burning of the candle is both a physical as well as a chemical change. The reactants are the substances or the raw materials that are required for a reaction to the process. In the process of burning a candle, the reactants are the fuel which includes wax and wick, and oxygen which is found in the air. The products found at the end of the reaction are carbon dioxide and water vapor.
