Answer:
6.11 J/g°C
Explanation:
We need to use the heat equation: q = mCΔT, where q is the amount of heat required in Joules, m is the mass in grams, C is the heat capacity, and ΔT is the change in temperature.
Here, we know q = 23,200 Joules, m = 28 grams, and the ΔT is just the difference of the temperatures: 150 - 14.4 = 135.6°C. Substitute these values to find C:
q = mCΔT
23,200 = 28 * C * 135.6
C = 6.11
Thus, the specific heat is 6.11 J/g°C.
Hello I took this test just now and got 100% your correct answer would be C. Hope this helps.
Temperature: a measure of the average kinetic energy of particles in an object
heat: the total energy of any closed system, including all internal kinetic and potential energy of the system
thermal energy: something that flows into a substance
Answer:a.Oxygen
Explanation:s you move from left to right, electronegativity increases. This means that oxygen is one of the most electronegative elements because it is situated on the right part of the periodic table. ... Oxygen has 6 valence electrons so it can still attract 2 more electrons to fill the valence shell.
