Answer:
Nothing
Explanation:
Thermal energy and heat are mainly related because of the fact that the faster molecules move, the more heat is created. If molecules are vibrating slower, that means that there will be less energy, resulting in less heat. Say I am boiling water. As the temperature increases, the water molecules move faster. Once that water cools, the molecules will be moving really slowly. In conclusion, thermal energy and heat are related because of how fast or slow the molecules move, the more or less heat and energy will be produced. I hoped this helped!
Answer:
ΔE = 5.02 x 10⁻¹⁹ j
Explanation:
ΔE (photon) = h·f = (6.63 x 10⁻³⁴ j·s)(7.57 x 10¹⁴ s⁻¹) = 5.02 x 10⁻¹⁹ j
h = Planck's Constant = 6.63 x 10⁻³⁴ j·s
f = frequency (given) = 7.57 x 10¹⁴ s⁻¹
Decrease in temperature is -126.0°C
<u>Explanation:</u>
Using Charles law we can set up the equation as,
V₁/T₁ = V₂/T₂
(2.00 L) / 294.0 K) = (1.00 L) / (x)
cross multiply to get:
2x = 294
2x/2 = 294/2
x = 147.0 K
Now kelvin is converted into Celsius by subtracting 273 from 147 as,
147 - 273 = -126°C
Answer:
B. The particles rarely touch each other.
Explanation:
The particles of gases are far apart, so they rarely touch each other. The particles of liquids can slide past each other, and the particles of solids are locked in place next to each other.
In all three states of matter, the particles
- Have a definite volume
- Are in constant motion
- Have kinetic energy
